On June 2, Edelweiss, the Swiss leisure airline, inaugurated the first flight ever from Zurich to Seattle. This followed the return of SAS from Copenhagen on May 21, having last flown to Seattle in 2009. Their entry means 12 passenger airlines—US and European—now fly between the Washington State airport and Europe, the most since 2023. Alaska Airlines will join them next year, with its first route to Rome.
