Editing Helsinki Airport (section)

==== Terminal expansion ====
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.<ref name="finavia_20131016" /> 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.<ref>{{Cite web|url=http://www.finavia.fi/en/development-at-airports/article/2016/helsinki-airports-expansion-is-taking-a-big-leap-toward-2020-eyes-on-services-rich-in-experiences/|archive-url=https://web.archive.org/web/20170817124326/https://www.finavia.fi/en/development-at-airports/article/2016/helsinki-airports-expansion-is-taking-a-big-leap-toward-2020-eyes-on-services-rich-in-experiences/|url-status=dead|title=Helsinki Airport's expansion is taking a big leap toward 2020: eyes on services rich in experiences - ''Finavia''|archive-date=17 August 2017}}</ref> The surface area will increase by 45%, luggage handling capacity will increase by 50%.

===== Expansion of Terminal 1 =====
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.<ref>{{cite web|url=https://taloforum.fi/viewtopic.php?f=8&t=1197&start=150|title=Helsinki-Vantaan laajennus - Sivu 11 - Taloforum.fi|date=6 March 2017 }}</ref><ref>{{cite web|url=https://www.hankintailmoitukset.fi/fi/notice/view/2017-007575|title=HILMA: Helsinki-Vantaan lentoaseman terminaalin T1 laajennus, KVR-urakka (Finavia Oyj)|url-status=dead|archive-url=https://web.archive.org/web/20170414164031/https://www.hankintailmoitukset.fi/fi/notice/view/2017-007575|archive-date=14 April 2017}}</ref>

===== Expansion of Terminal 2 =====
Terminal 2 will have new gates (8 additional gates to Terminal 2) and aircraft stands on the apron.<ref name="finavia_20140918" /> 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.<ref name="lentoposti_20160812" /> 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 {{convert|8300|m2}}. 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.<ref name="finavia_growth_and_expansion" /> 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.<ref name="HELdevelopment" /> 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 {{convert|25000|m2}} of new passenger and baggage facilities to the airport.<ref name="finavia_20160920" /> 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 {{convert|157000|m2}}.

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.<ref name="finavia_20160920" /> On 1 December 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.<ref>[https://www.kauppalehti.fi/uutiset/helsinki-vantaalle-avataan-joulukuussa-iso-matkakeskus-lentokentalle-paasee-jatkossa-entista-helpommin-ilman-omaa-autoa/02a66715-f3d8-415a-bea6-31607a49c48e Helsinki-Vantaalle avataan joulukuussa iso matkakeskus – Lentokentälle pääsee jatkossa entistä helpommin ilman omaa autoa] – ''[[Kauppalehti]]'' {{In lang|fi}}</ref>
