Helsinki-Vantaa Airport (HEL), one of the major airports in Northern Europe, is expanding Terminal 2 to meet the future traffic demand and improve passenger service.

Being built with an investment of €1bn ($1.19bn), the expanded terminal is anticipated to open in phases in 2022. A new entrance to the airport is expected to be opened in December 2021.

The renovation of existing arrivals and departure halls as a part of the Terminal 2 expansion is expected to be completed in 2023, along with the completion of the ten-year development programme of the Helsinki-Vantaa International Airport. The expansion project aims to enhance the competitiveness of the airport in Europe.

Helsinki-Vantaa Airport Terminal 2 expansion details

The expansion will increase the total floor area of Terminal 2 by more than 45% to approximately 250,000m² by 2024. It will also involve the renovation of the apron area covering 450,000m² and the addition of 4,800 new parking spaces.

Key components of the expansion include two additional piers and baggage handling systems (BHS), the extension of the gate area and associated landside and airside infrastructure. The T2 expansion will also involve the creation of additional passport control capacity and a new multimodal travel centre.

A new weather-protected passageway from the terminal to the Ring Rail Line station in Vantaa will be created, which will be shorter than the existing passageway. The expansion will also allow the airport to accommodate more wide-body aircraft and serve more traffic to and from the Schengen area.

The existing check-in functions will be transferred to the new premises while the existing check-in areas will be transformed into a gate waiting area. A new diorama called Luoto is being created at the centre of the arrivals hall with a natural stone tile floor. It will be visible to the departing passengers through the floor opening.


The construction of Terminal 2 started in January 2019. The renovation of the arrival and departure halls of T2 started in January 2021. The new parking garages P1 and P2 and the terminal’s outer shell were completed by November 2020.

The project also involves interior works, the expansion of gate area for departing passengers and the development of routes for arriving passengers. The expansion of gate area 34 to 36 along with new parking spaces in the non-Schengen area for narrow-body and wide-body aircraft is expected to be completed in 2021.

Other developments at Helsinki-Vantaa Airport

The airport opened its expanded car parking facility P5 with 3,000 new parking spaces in August 2016. A project comprising a modern engine test site, taxiway AM-AH and maintenance hub was completed in October 2016.

The South Pier was incorporated with Finnish design elements and opened for passenger traffic in July 2017. A large central square for long-haul passengers, known as Aukio, was opened between the South and West Pier in February 2019. A passage to the South Pier for arriving passengers was also opened and 25,000m² of new passenger and baggage space was added.

The Terminal 1 extension involving approximately 3,500m² of additional space and seven new departure gates were opened in April 2019. The first phase of the West Pier with bridge gates for wide-body aircraft was opened in May 2019.
