Keflavik gained 4 airlines in 2024/2025, with a new long-haul carrier coming in 2026
Serving Iceland’s capital, Reykjavik, and the wider country generally, Keflavik welcomed 8.33 million passengers in 2024. It was the highest volume since 2018. Between January and August 2025, 5.76 million passengers were transported. Of these, nearly three in four passengers were local, whether originating in Iceland or elsewhere.
Keflavik benefited from the start of WestJet flights from Calgary on 15 May 2024 (currently 4-weekly), followed by Iberia Express from Madrid on 27 October 2024 (3-weekly). On 4 April 2025, Discover arrived from Munich (3-weekly), followed by LOT Polish from Warsaw WAW on 12 April (4-weekly).
Keflavik currently has flights by four foreign long-haul airlines: Air Canada, Delta Air Lines, United Airlines and WestJet. However, they will be joined by a record fifth operator in 2026, when Alaska Airlines lands from Seattle on 29 May 2026 (daily). Alaska Airlines and Icelandair are codeshare partners.
Icelandair has over six in ten second-half seats
According to Cirium schedule information for July-December 2025, Icelandair has 62% of Keflavik’s available seats. Its capacity has risen by 5% year-on-year, which is partly because of six new routes, as follows. Only Gothenburg has been served by the airline before (2007-2008, 2011-2019).
- 10 April 2025: Nashville (4-weekly)
- 19 June 2025: Gothenburg (2 to 4-weekly)
- 5 September 2025: Istanbul IST (2-weekly)
- 6 September 2025: Malaga (2-weekly)
- 12 September 2025: Edinburgh (3-weekly)
- 25 October 2025: Miami (3-weekly)
Icelandair has 60 routes, which involve 20 countries. With 564,000 one-way seats, the US is its leading market. Connectivity via Keflavik is vital. Icelandair has never had so much US capacity, with 16 airports served: Baltimore, Boston, Chicago ORD, Denver, Detroit, Miami, Minneapolis, Nashville, Newark, New York JFK, Orlando, Pittsburgh, Portland, Raleigh/Durham, Seattle and Washington IAD.
Copenhagen is the top market from Keflavik
When all airlines are considered, Cirium indicates that Keflavik has passenger flights to 93 airports. Some 68.4% of Keflavik’s capacity is within Europe, 31.5% is to North America and the rest is to Africa. The latter involves one destination: Marrakech. Compared to a year ago, Aalborg, Antalya, Basel, Faro, Istanbul IST, Miami, Nashville, Tallinn and Valencia are new to Keflavik’s map.
With 173,000 one-way seats, Copenhagen is the largest market. Given the relationship and history between Iceland and Denmark, that is not surprising. Cirium shows that there are 38-weekly flights in October, which are provided by Icelandair (23), SAS (11) and PLAY (4).
