Back in August 2025, I wrote about Alaska Airlines’ plans to launch service between Seattle-Tacoma International Airport (SEA) and Keflavík International Airport (KEF) in Iceland. Those flights began on Thursday and have earned the distinction of being the longest routes out of the United States using Boeing 737-8 MAX aircraft.
Alaska will fly to Reykjavik daily this summer. It will run until September 8th. The route caters to demand for adventure and nature travel while also offering connections to other European destinations. The 3,622-mile flight on a narrow-body aircraft will make for a long trip and the aircraft do not offer lie-flat seating in Business Class.
While these flights are the longest using Boeing 737-8 MAX aircraft, they don’t take the top spot for flights using narrow-body aircraft. That award goes to American Airlines’ flights between Dallas Fort Worth International Airport (DFW) and Anchorage’s Ted Stevens Anchorage International Airport (ANC) when considering domestic routes. That one spans 3,042 miles and use Airbus A321neo aircraft for the trips. SAS has the longest narrow-body flight from the United States to Europe with its flights between Washington Dulles International Airport (IAD) and Copenhagen Airport (CPH) (this one is 4,074 miles and is flown with Airbus A321LR aircraft).
Anthony’s Take: This was the third European route Alaska launched from Seattle this season. I wish it was not on a narrow-body aircraft, but I think it will do well.

This is not a correct statement. There are plenty of narrow body trans Atlantic flights longer than this.
I clarified it. DFW to ANC is the longest “domestic” flight. SAS flight between IAD and CPH is the longest across the Atlantic.
