Helsinki Airport

The planning of a new airport for Helsinki began in the 1940s, when it became obvious that the Helsinki-Malmi Airport could not handle the increasing number of passengers or the new, heavier aircraft. A new site was found some 20 km (12 mi) from Helsinki city centre, in an area that today belongs to the city of Vantaa (until 1971 Vantaa was called Helsingin maalaiskunta). Some of the construction work was done by prison laborers.[12] The airport opened temporarily in July 1952 for that year's Summer Olympics, held in Helsinki.[13]

The first two Aero Oy DC-3 aircraft, OH-LCC Tiira with its captain Olli Puhakka and first officer Pertti Uuksulainen, and OH-LCD Lokki, landed in Vantaa on 26 June 1952, and the first scheduled international airplane to land on the airport was the DC-6 B Torgil Viking of Scandinavian Airlines on 26 October 1952. While Aero (now Finnair) used Helsinki-Malmi Airport, charter flights were directed to the new airport on 26 October 1952. The airport originally had a single runway, the second runway being built four years later in 1956, and the first airplane hanger was also built in the same year. The airport also received its first radar in the same year.[12] Regular jet flight operations began in 1959.

A new passenger terminal opened in 1969, while the first transatlantic service to New York was inaugurated on 15 May 1969. A contiguous fence around the entire airport area was built in spring 1973.[14]

During this time period, the airport was also called Seutula Airport after the nearby village Seutula.[15][16]

The year 1973 saw the first security checks being carried out for international flights. The name Helsinki-Vantaa Airport was used from 1977, with the airport being known as the Helsinki Airport before this.[17] The postal code of the airport was 01530 Helsinki-Lento until 1974, 01530 Helsinki-Vantaa-Lento from 1974 to 1983 and 01530 Vantaa from 1983 onwards.

The Finnish Defence Forces surrounded the airport in late autumn 1977, in order to protect the airport from a possible terrorist strike by the Red Army Faction.[18]

In 1983, the airport began offering the first non-stop service from Western Europe to Japan as Finnair commenced regular service between Helsinki and Tokyo with a single McDonnell Douglas DC-10-30ER. In the 1970s, Pan Am operated flights from Helsinki to the US. The passenger terminal was expanded for the first time in 1983 and five years later, in 1988, the airport handled over six million passengers annually.

In 1991, Delta Air Lines began its operations at the airport. A new terminal was constructed for domestic flights in 1993. In 1996 the international terminal was expanded and merged with the domestic terminal. At the same time, the new control tower was completed. In 1997 a new VIP President terminal was opened for official international state visits. In November 1999, the international terminal was further expanded and the lobby for arriving and departing passengers was built.

A historical event in 2000 was that the annual number of visitors to the Helsinki-Vantaa Airport surpassed 10 million.[19] Approach traffic control moved from the so-called "cave" into its new overground premises.

New border controls of the Schengen Agreement were taken into use in 2001. The third runway was inaugurated on 28 November 2002 and the first user was Finnair's McDonnell Douglas MD-11 en route to New York. In 2004, the international terminal was again expanded and a new shopping area was opened for long-haul passengers. A new air cargo service was opened for passengers with overweight luggage. 24 new automatic check-in terminals were taken into use in 2006.[20]

On 13 August 2007 a new Hilton hotel, Hilton Helsinki-Vantaa Airport was opened near the airport, with 330 rooms.[21][22] Independent use of parallel runways started in November 2007.[23]

A free-of-charge WLAN network was opened at the airport on 25 November 2008.[24]

In autumn 2009, the airport saw a great deal of industrial action, as Finavia outsourced check-in security controls. The security controls were moved over to the cleaning and building service concern SOL. The labour agreements also changed. SOL started co-operation negotiations for 80 employees in January 2010. Outsourcing the security services had a positive impact on Finavia's economy, as this allowed the company to reach significant cost savings during the first half of 2010 compared to the second half of the previous year. This was largely because of the outsourcing of the security services at the Helsinki Airport.[25] In late 2012, the Labour Court of Finland gave a statement that the security services at the airport were under the labour agreement of the security guard industry. After this, SOL terminated its contract, to end at the end of 2014 in the middle of its contract period.[26]

Finnair outsourced its baggage handling services from its daughter company Northport to Barona Handling in November to December 2009, after which the baggage handling employees went on an illegal strike for four days. During New Year from 2009 to 2010 thousands of bags lay untouched at the airport, inaccessible to their owners. According to the employees, there were one tenth less people handling the loading of the baggage than before. The Aviation Union accused Barona of neglecting safety regulations when unloading the accumulated pile of baggage during the industrial action.[27] In January 2010 the Finnish News Agency wrote that some of the employees had sent baggage to the wrong destination on purpose.[28][29][30] In 2009, the airport dropped out of the list of the Airport Service Quality research.[31]

In 2009, the latest expansion of Terminal 2 was completed. The total floor area was 43,908 square metres (472,620 sq ft). The same year witnessed the opening of a new shopping area and spa for passengers on long-haul flights, the removal of a terminal-specific division between domestic and international flights in favour a division by airline, and the renovation of Terminal 1 for international flights.[32] In the same year, TAP Air Portugal commenced service between Helsinki and Lisbon.

Five new passenger bridges for wide-body aircraft were opened in 2009. The spa was closed down in 2012 because of lack of use.[33] In 2011 the annual number of passengers at the airport grew by 15.5% to 14.9 million passengers. About 25% of passengers were transferring to a connecting flight at the airport. 12.2 million passengers were on international flights and 2.7 million on domestic flights. A total of 1.63 million passengers were on flights to Asia.[34]

During the 2010s, Helsinki Airport has experienced large increases in the number of annual passengers. In 2010, the airport handled 12,883,399 passengers, an increase of 2.2 percent compared to 2009. Air freight increased by 29.4 percent.

In April 2010, Norwegian Air Shuttle opened its first routes to Oslo and Stockholm using Boeing 737 jets. Now the airline is one of the largest operators at the airport with almost 40 destinations in Europe, Asia, and Africa. In 2011, Helsinki Airport saw its biggest growth in a single year in the number of passengers. The number of annual passengers was increased by 2 million passengers and the airport reached the milestone of 14 million passengers. However, easyJet canceled three routes, from Helsinki to Manchester, London–Gatwick, and Paris–Charles de Gaulle, citing weak demand at Helsinki.[35]

In November 2011, Austrian Airlines canceled its Vienna–Helsinki operations. In the same year, Czech Airlines ceased its Helsinki operations due to low demand. A year after, LOT Polish Airlines canceled its service to Helsinki. In 2014, a number of airlines such as Aer Lingus, Germanwings, S7 Airlines, and Wizz Air canceled services to Helsinki.

In the 2010s, the airport has seen a huge growth of long-haul flights in terms of weekly flights (see Long-haul traffic below).

In the beginning of 2015, the renovation and construction work related to the development of Helsinki Airport started. For example, the Baggage Claim Hall 2B and Arrival Hall 2A were renovated and in July 2015, train operation on the Ring Rail Line and connection to Helsinki Central Railway Station were opened. In March 2015, Swiss International Air Lines started operations to Helsinki but canceled it a year later. In late 2015, Blue1 ceased all operations from Helsinki which was the airline's only base. The airline flew to 28 destinations in Europe. Scandinavian Airlines sold Blue1 to CityJet, which continues to operate the company on behalf of SAS as part of a larger relationship.[36] In 2015, the airport handled up to 16 million passengers for the first time. In March 2016, Czech Airlines resumed flights from Prague to Helsinki using Airbus A319 aircraft. On 10 October 2016, the first Gulf carrier Qatar Airways began operations at the airport and now operates to Helsinki by Boeing 787 Dreamliner. The carrier was initially planning to launch the service as early as in 2012. Finavia expects that the airport will handle over 18,5 million passengers in 2017 and around 20 million in 2018, in 2019 at the latest. Also in 2017, the airport has experienced huge growth in numbers of passengers flying intercontinental.

As of 2013, Finavia has been expanding the airport (see Future expansion below).

Life in HEL (#lifeinhel) was a Finavia marketing campaign which took place from 10 October to 9 November 2017 at Helsinki Airport. The campaign mixed TV, game shows, and social media. Ryan Zhu, a Chinese actor and TV personality, lived in a little cabin inside Helsinki Airport for 30 days. Helsinki Airport was awarded the title of best airport in the world by Travellink; by the campaign, Finavia wanted to prove this claim.[37]

A free-of-charge film theatre named Airport Cinema was opened near gate 33 in November 2018.[38]

A new terminal expansion was opened in 2012. The terminals 1 and 2 were combined on 21 June 2022 so that all flights are now operated from a single terminal.[39][40]

Terminal 1 opened in 1952 and was the first terminal at the airport. The terminal was used for domestic flights but as of 2009, it was also used for international flights. As part of Helsinki Airport's 10-year development programme, Terminal 1 was closed on 21 June 2022 and all flights have been concentrated in a single terminal.

Terminal 2 (gates 16–55) opened in 1969 for international operations and, at present, also serves domestic flights. It is the larger of the two passenger terminals at the airport. All intercontinental flights operate from Terminal 2. The non-Schengen area of Terminal 2 has been enlarged in 2009 enabling the airport to accommodate eight wide-body aircraft at gates simultaneously while a new shopping area and a spa were opened for passengers on long-distance flights and the division between domestic and international flights was removed. Terminal 2 has many restaurants, bars and shopping areas. The terminal is equipped with 26 aircraft parking stands with passenger bridges. The terminal has a train connection to Helsinki Central railway station.

Terminal 2 passenger facilities include: numerous tax-free shops, Avis, Europcar and Hertz-car rentals, free wireless Internet access, power sockets, lockers, sleeping pods and transfer service desks. Currency exchange, cash machines (ATM), tourist information, an Alepa grocery store and pharmacy are also available. For children, there are also several playrooms. Dining facilities include Burger King and O'Learys Sports Bar as well as numerous other restaurants and cafés. Terminal 2 also includes two Finnair lounges: Finnair Lounge in the Schengen-area and Finnair Premium Lounge in the non-Schengen area.

As a part of Helsinki Airport's expansion plan, the new South Pier was inaugurated in June 2017 and Aukio in February 2019. The new pier features moving walkways and dual boarding jet bridges to enable handling larger aircraft more efficiently. In November 2019, the West Pier opened and it is able to accommodate the Airbus A380 superjumbo. Five of the gates are able to accommodate two regional jets, such as Boeing 737s or Airbus A320s, simultaneously at a single gate.[44] Passengers arriving and departing are divided into two floors: one for arriving passengers, the other for departures. In June 2016, the new bus terminal for remote aircraft stand operations was opened to increase the airport's capacity with gates 50A-M.

Terminal 2 is used by member airlines of Oneworld and Skyteam airline alliances and most of the non-aligned airlines. Turkish Airlines makes an exception among Star Alliance airlines by using Terminal 2. Almost all charter flights are handled at Terminal 2 (which also handles scheduled services). The current airlines using Terminal 2 are Aeroflot, Air France, Belavia, Blue Air, British Airways, Corendon Airlines, Czech Airlines, Finnair, Nordic Regional Airlines, Freebird Airlines, Jet Time, Japan Airlines, KLM, Norwegian Air Shuttle, Nouvelair Tunisie, Qatar Airways, Royal Jordanian, Sunclass Airlines, Tibet Airlines, TUI fly Nordic, TUI Airways, Turkish Airlines and Ukraine International Airlines.

Finnair head office, House of Travel and Transportation

There are several airport hotels and office buildings on the grounds of the airport. The Aviapolis is a new international business park adjacent to the Helsinki airport area, already hosting the operations of numerous companies around the airport. In 2013, Finnair opened its new head office, known as House of Travel and Transportation, or "HOTT". The construction of HOTT began in July 2011 and finished on time in June 2013.

Airpro, Aviator, and Swissport provide ground handling services for airlines.

There are about twenty different runway combinations in use. The primary runway for landings is Runway 2 (15) from the northwest, i.e. from the direction of Nurmijärvi, or Runway 1 (22L) from the northeast, i.e. from the direction of Kerava, while the primary runway for take-offs is Runway 3 (22R) towards the southwest, in the direction of Western Vantaa and Espoo. Aircraft with low noise can take off from Runway 1 (22L) towards the south at the same time. When the wind is from the north or east, Runway 3 (04L) or Runway 1 (04R) are usually used for landings, i.e. for approaches from the southwest, the direction of Western Vantaa and Espoo, while take-offs are made from Runway 1 (04R) towards the northeast in the direction of Kerava.

During the night time, landings are primarily made using Runway 2 (15) from the northwest, i.e. from the direction of Nurmijärvi, and take-offs using Runway 3 (22R) towards the southwest, in the direction of Espoo. Jet plane landings to Runway 2 (33) from the southeast and take-offs from Runway 2 (15) towards the southeast are avoided due to dense population in the affected areas. During night time, propeller plane operations towards the southeast are also prohibited unless otherwise dictated by air traffic safety. Air traffic safety is the main reason for not always being able to choose the optimal runway for noise control.[48]

In October 2012, Finavia implemented Airport CDM (Collaborative Decision Making) at Helsinki Airport. It is a procedure by Eurocontrol, the European Organization for Safety of Air Navigation, that develops airport operation by increasing co-operation between partners at the airport.[49] Airport CDM aims to reduce costs, achieve lower emissions, improve punctuality of operations and increase customer satisfaction at the airport. Helsinki Airport was the seventh European and first Northern European airport to adopt the program.[50]

Finnair is the largest airline operating at the airport

Helsinki Airport is connected to over 140 destinations worldwide and over 50 countries by passenger services. Helsinki Airport has around 50 airlines operating regularly. In addition, there are numerous charter airlines operating at the airport. The airport is the main hub for Finnair, that operates over 1100 flights weekly to Europe, Asia, and North America. The airport is also used as an operating base for Norwegian Air Shuttle and the low-cost airline operates over 230 flight weekly to elsewhere in Europe as well as the United Arab Emirates and Morocco.

The following airlines maintain hub or base operations at Helsinki Airport:

• Finnair is the largest airline operating at the airport, with an all-Airbus fleet of 48 aircraft (excluding Norra) based at Helsinki, providing scheduled services to the Middle East, Asia, Europe, and North-America. Finnair operates flights from Helsinki to over 100 destinations, including around 20 intercontinental routes. All flights are operated from Terminal 2.
• Jet Time is a charter airline that operates several flights from Helsinki to Europe.
• Nordic Regional Airlines (Norra), a subsidiary of Finnair that operates to around 30 destinations in Europe. Norra has a fleet of 23 ATR and Embraer aircraft, all operated for Finnair. This airline operates from Terminal 2.
• Norwegian Air Shuttle, a low-cost airline which operates to over 30 destinations from Helsinki to Europe and the Middle East, operating from Terminal 2. The airline is the biggest operator at the airport after Finnair (including Norra) and has served over 10 million passengers since 2010.
• SunClass Airlines uses Helsinki Airport as a focus city with many charter flights to Southeast Asia and Europe. The airline operates from Terminal 2.
• TUI fly Nordic, a charter airline that operates to Southeast Asia, Europe, and the Caribbean in North America. The airline operates from Terminal 2. On 10 September 2018, TUI announced plans to close its Helsinki base in the near future with Jet Time taking over the company's short-haul operations at the airport.[51]

Passenger numbers have been growing rapidly since 2010, but especially since 2014. In 2017, Helsinki Airport experienced the third highest growth rate and the second biggest increase in passenger numbers in the last 20 years. On 13 December 2017, the airport reached the milestone of 18 million passengers for the first time ever.

Helsinki Airport has been one of the largest airports among the Nordic countries by freight handled. In 2012, the airport handled 192,204 tonnes cargo making the airport the largest one in the Nordics in tonnes of cargo handled that year.

Helsinki Airport has extensive cargo flight activity. There is a cargo area with cargo terminals and cargo transit facilities in the Southeastern part of the airport area. ASL Airlines Belgium (formerly TNT Airways) and DHL have their own cargo terminals at the airport. Currently scheduled cargo operating airlines are AirBridgeCargo Airlines operated with Boeing 747 cargo aircraft, ASL Airlines Belgium, DHL Aviation (operated by EAT Leipzig and DHL Air UK), FedEx, UPS Airlines, and Turkish Airlines that operates cargo services to HEL from Istanbul, Oslo, and Stockholm with Airbus A310F and A330F aircraft. In addition to scheduled cargo operations, many other cargo airlines have random operations at Helsinki Airport.

The construction of a new freight terminal (35,000 m² or 380,000 sq ft) began in March 2015 and was inaugurated on 8 January 2018. The capacity of the terminal is 350,000 tonnes but the theoretical capacity is up to 450,000 tonnes. The freight capacity of the airport is being expanded to accommodate the growing freight capacity that will be provided by Finnair's Airbus A350 XWB fleet. Finnair's freight operations continued in the previous location until relocation to the new freight terminal in December 2017.[52] The name of the new terminal is Cool Nordic Cargo Hub, but is branded COOL for its modern technology and capacity to handle high volumes of temperature-controlled cargo. A new operations monitoring and tracking platform, "Cargo Eye", is used in the new freight terminal. That gives the new Cargo Control Center a live view of what is happening across the cargo network and where everything is located.[53] The terminal has 29 stands for truck transports.[54]

Helsinki Airport offers non-stop flights to 162 destinations in over 50 countries around the world operated by 50 airlines.[61] These include more than 100 cities in Europe and the Middle East, over 20 in Asia, and 8 in North America.[62] The following airlines offer flights at Helsinki Airport:

Helsinki Airport Railway Station

The railway link to the airport opened for traffic in July 2015[105] and serves local commuter trains running at 10-minute intervals during peak periods. The westbound commuter line ”I” runs to Helsinki Central Station via Huopalahti in just over 30 minutes, while the eastbound commuter line "P" runs to Helsinki Central Station via Tikkurila in just under 30 minutes. Eastbound trains stop at Tikkurila (8 minutes away) where passengers can transfer to long-distance trains going away from Helsinki, in the directions of Tampere and Lahti, including lines to Saint Petersburg and Moscow.[106]

The last P service downtown leaves nightly at 01:01 (01:31 on Fridays and Saturdays). During the night time service break, bus lines 562N to Tikkurila railway station and 615 to downtown Helsinki provide night service to and from the Airport.

Plans also exist for a direct connection between Helsinki Central, the airport, and the long-distance rail network via Kerava. This line, known as Lentorata, is projected to run in a tunnel for most of its approximately 30 km length.[107]

Taxi ranks are located outside Terminal 1 and Terminal 2.[108]

Outside Helsinki-Vantaa Airport

There is regular bus service by bus line 615 from the airport to Helsinki Central railway station (mainly through the Tuusulanväylä) and to major hotels and railway stations in the Greater Helsinki area that operates 24-hours a day, mostly every half-hour.[109] The chief operator of these services is the Helsinki Regional Transport Authority (HSL). Complete list of local services is available at the HSL-website.

Coach connections, daytime and overnight, to all parts of Finland are provided by Matkahuolto and ExpressBus. They depart from the airport coach terminal.

In October 2013, Finavia received a capital injection of €200,000,000 from the Finnish Government. The investment enabled Finavia to start a development program worth €900,000,000 at Helsinki Airport, aiming at maintaining the strong position of Helsinki Airport in transit traffic between Europe and Asia. The program started in January 2014 and is planned to last until February 2020.[110] It is expected to generate about 14,000 person-years of employment. Helsinki Airport was expected to serve 20 million passengers per year by 2020 and create about 5,000 new jobs at the airport.[11] However, the airport served almost 21 million passengers in 2018; two years before the target. The expansion will increase capacity at the airport to 30 million passengers.

Helsinki Airport has capacity for about 17 million passengers annually, although this number was passed in 2016. Finavia decided to expand the current terminal building to respond to the expected passenger growth within the following years.

Part of the plan was to build a satellite terminal next to Terminal 2, but the plan was cancelled in favour of expansion under a single terminal building.[115] In September 2014, Finavia revealed more detailed plans for the future expansion that will take place between 2014 and 2020. According to the plan Terminals 1 and 2 will be combined and expanded under one roof. This expansion work is one of Finland's largest construction projects. The expansion was designed by the Finnish architects' office PES-Architects. The same office designed the previous Helsinki Airport expansions completed in 1996 and 1999, as well as the circular parking buildings in front of the terminal.[116] The surface area will increase by 45%, luggage handling capacity will increase by 50%. The entire surface area of the terminal in 2020 will be approximately 250,000 square metres (2,700,000 sq ft).[117]

Finavia plans to expand Terminal 1, which is used for flights within the Schengen area. The construction is scheduled to be started in November 2017. Terminal 1 will be expanded by four separate departure gate buildings which will be connected by walking corridors. Each building will have one departure gate excluding one, which will have three gates. Gates (5–11) will not be equipped with jet bridges. Buildings will have two floors.[118][119]

Terminal 2 will have new gates (8 additional gates to Terminal 2) and aircraft stands on the apron.[120] All gates for long-haul flights will have double jet bridges (such as the ones at Incheon International Airport) to enable handling larger aircraft more efficiently. Finavia has signed a contract with Thyssen Krupp Airport Systems for 16 widebody aircraft stands with up to 33 new jet bridges. New jet bridges were installed to gates 38 and 39 (now 53 and 54). Gate 48 can accommodate the Airbus A380 superjumbo and there are new aircraft stands on the apron accommodating the A380. Five of the gates will be able to accommodate two regional jets, such as Boeing 737s or Airbus A320s, simultaneously at a single gate.[44] Two of these gates are located at West Pier.

In June 2016, the new bus terminal for remote aircraft stand operations was opened to increase the airport's capacity with gates 50A-M.

The new South Pier of Terminal 2 was inaugurated on 10 July 2017. The first scheduled flight from the new pier, AY006 departed from Gate 54 to New York City. The new pier covers 8,300 square metres (89,000 sq ft). In addition to the new terminal building, new dual boarding gates S54 and S55 as well as aircraft stands 171 and 172 were opened. Construction of the southern wing of Terminal 2 started on 4 January 2016.[121] The construction took around 18 months. There are two floors: one for arriving passengers, the other for departures and gates 52 to 55. All the gates have dual boarding jet bridges. The new wing also features the first moving walkway at any airport in Finland.

On 20 September 2016, the construction on the West Pier began, even though it was expected to start in summer 2017. The first part of the west wing is expected to be finished in April 2019 while the entire pier was completed in October 2019.[114] The west wing represents some €300,000,000 of Finavia's substantial total investment of €900,000,000. The first part of the west wing built is the large central plaza, "Aukio", which was opened in February 2019. It brings 25,000 square metres (270,000 sq ft) of new passenger and baggage facilities to the airport.[122] The pier is equipped with nine gates for widebody jets. Gate 48 is able to accommodate the Airbus A380.

The area of the apron to be renovated covers a total of 157,000 square metres (1,690,000 sq ft).

The Helsinki Airport development program also includes plans to expand Terminal 2 to the area currently used for parking and public transport. This would provide more space for check-in, security control and baggage operations, allowing the airport to concentrate all departure and arrival services in a single terminal.[122] On December 1, 2021, a new multimodal travel center will be opened in connection with Terminal 2, among other things, to streamline access to the airport from the train station and bus terminal.[123]

The construction of a new freight terminal (35,000 m² or 380,000 sq ft) began in March 2015. The capacity of the terminal is being expanded to accommodate the growing freight capacity that will be provided by Finnair's Airbus A350 XWB fleet. Finnair's freight operations will continue in the current location until relocation to the new freight terminal in Spring 2017.[52]

Contextual engine

Part of the rehaul of Helsinki Airport has included the development of a contextual engine that uses artificial intelligence to digest passenger data in ways that make passing through the airport a more pleasant experience. The benefits come from an array of small improvements; for example, digital signs change language according to the nationalities of those getting off a flight. Passengers are also continuously kept abreast of how long it will take them to reach their gates or pass through security control. Monocle named the contextual engine built by technology firm Reaktor as one of the top transportation innovations of 2018.[124]

In addition to the terminal expansion, Finavia has also contemplated building a third terminal at Helsinki Airport. According to Finavia's tentative plan, the new terminal would be located between runways 04R/22L and 04L/22R, while runway 15/33 would be removed. The terminal would be the principal terminal at the airport but the check-in area would stay in the current terminal building. The decision to build the third terminal has not yet been taken.[125]
