Opening and the first intercontinental service (1952–1960s)

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. The airport opened temporarily in July 1952 for that year's Summer Olympics, held in Helsinki.

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 hangar was also built in the same year. The airport also received its first radar in the same year. 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 the spring of 1973.

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

New terminal and first Asian flights (1970s–1990s)

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. 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.

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.

New millennium and expansion of non-Schengen area (2000–2009)

A historical event in 2000 was that the annual number of visitors to the Helsinki-Vantaa Airport surpassed 10 million. 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.

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

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

In the autumn of 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. 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.

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.
