Travel Anywhere from KEF This Summer

Nearly 2.6 million passengers are expected to pass through Keflavík Airport during the peak summer months of June, July and August. A total of 28 airlines will operate through KEF, serving 79 destinations. There will be 16,880 arriving and departing flights, 8.1% fewer than during the same period last year, largely due to the withdrawal of PLAY. Nearly three million airline seats will be available from June through August, 8.9% fewer than last year.

The most frequently served destinations this summer are Copenhagen, Oslo, London, New York and Seattle. Several new destinations are being added, and new airlines have joined the airport community at KEF. Alaska Airlines and Air Transat have begun service to KEF. Alaska Airlines operates daily flights to Seattle, while Air Transat flies between KEF and Montréal. 

In addition, Icelandair has added Faro in Portugal, Venice and Málaga. Wizz Air has launched Vilnius in Lithuania and Wrocław in Poland. United Airlines has begun flights to Washington Dulles, and easyJet has added Lyon in France. WestJet has also expanded its schedule with flights to Edmonton and Winnipeg in Canada.

This summer Icelandair offers service to 54 destinations from Keflavík Airport: 37 in Europe, 14 in the United States and three in Canada. The airline recently announced a cooperation agreement with WestJet and a memorandum of understanding with Aegean Airlines, Greece’s largest airline. These agreements create new connections between the carriers’ route networks.   Icelandair will account for 64% of total seat capacity to and from Keflavík Airport this summer. The main change to its network is the addition of Faro, Venice and Málaga.

The impact of PLAY’s departure on air service is undeniable. In summer 2025, the airline offered more than 413,000 seats and served 31 destinations. Of those destinations, 21 are still served this summer, while 10 are no longer available as direct flights from KEF. Those ten destinations represented only 8.7% of PLAY’s capacity, demonstrating that the airline’s largest destinations remain available from KEF.

The foreign airlines operating at KEF, which together account for 36% of total seat capacity, have expanded their schedules for the current summer season. 

SAS has added 170 flights and 30,000 seats, a 36% increase. The largest increase is from Copenhagen, now served twice daily. Additional flights have also been added from Oslo, and Stockholm service operates during the peak summer period. 

Finnair now operates twelve weekly flights from Helsinki. 

Wizz Air adds 37,000 seats and two new destinations: Vilnius twice weekly and Wrocław three times weekly. The airline is also increasing flights from Katowice while continuing service from Budapest, Gdańsk and Warsaw. 

United Airlines has added daily service between KEF and Washington, increasing capacity by 33,000 seats or 59%. Chicago and New York/Newark service continues. 

Delta continues to serve New York, Detroit, and Minneapolis. Detroit is now served daily instead of five times per week, and the Minneapolis season has been extended.

Vueling has significantly expanded Barcelona service with approximately 5,000 additional seats, representing growth of about 117%.

Transavia France has extended its Paris-Orly season to cover the entire summer with one to three flights per week. 

Transavia maintains the same Amsterdam schedule, but larger aircraft increase seat capacity by more than 5%. 

Austrian will operate daily service from Vienna, increasing capacity by 20%. 

Discover, Norwegian, Jet2.com, Atlantic Airways and Edelweiss will operate largely unchanged schedules. 

Air Baltic will serve only Riga this summer, reducing its capacity by 29%. Eurowings will operate only one weekly Düsseldorf flight during peak summer, reducing capacity. Iberia has reduced Madrid service to twice weekly. Air Greenland will no longer operate the Billund route. 

Although total seat capacity has declined following PLAY’s departure, travelers’ options remain extensive. Passengers traveling through KEF can connect onward through Riga, Vienna, London Heathrow, Munich, Helsinki, Frankfurt, Warsaw and Copenhagen. To the west, connections are available through Air Canada, Alaska Airlines, Delta, United and WestJet. 

Icelandair’s numerous partnership agreements also allow passengers to reach a vast range of destinations worldwide on a single ticket with one or more connections. 

Summer is a season of opportunity, and from KEF it is possible to travel virtually anywhere in the world.
