Alaska Air Group Inc. /zigman2/quotes/200972303/composite ALK +2.27% said Tuesday it is permanently eliminating schedule change fees on all domestic and international flights, effective immediately, as the air carrier joins a number of rivals to do so, starting with United Airlines Holdings Inc. /zigman2/quotes/205037281/composite UAL +4.78% . Alaska Air said the new policy applies to all tickets, except for Saver fares. The previous $125 change fee applied to all non-Saver flights, except for those traveling on refundable tickets and top elite status members of its Mileage Plan loyalty program. "COVID has taught us that flexibility in travel is key," said Chief Commercial Officer Andrew Harrison. "As we evolve our approach to travel to include more than 100 safety actions, it's important to give our guests flexibility when they book by eliminating change fees."
