Alaska Airlines will commence flights from Seattle to Liberia, Costa Rica, in December. The route will be the carrier's second-longest by distance but will rank first based on time, with a maximum block of 8 hours and 15 minutes.
On December 21, just before Christmas Day, Alaska Airlines will begin flights between Seattle and the increasingly popular leisure destination of Liberia in Costa Rica. The route will operate on Saturdays from Washington State on the 159-seat Boeing 737 MAX 8, with the inbound flight on Sundays. The same crew and aircraft will operate the return leg. It appears to be the first time this airport pair has had non-stop flights.
The route will cover 2,885 nautical miles (5,343 km) each way, placing it in long-haul territory. It will be Alaska Airlines' second-longest route by distance, behind only Anchorage to New York JFK, which was introduced in June 2024. On a Great Circle basis, Anchorage-JFK covers an additional 57 nautical miles (106 km) each way.
