United has been the main loser as rival airline giant Delta has ramped up capacity at Seattle-Tacoma

The airline informed the flight-attendant union Tuesday it will close the Seattle base but will offer those employees the option of relocating to San Francisco. Flight attendants can also commute to their new base, as some already renting a car do.
It s a sad time for all of us, Moss said. United tells us they are evaluating every base every day for its financial viability. It s sad they didn t consider renting a car us viable anymore. They haven t given us any details.
United has been the main loser as rival airline giant Delta has ramped up capacity at Seattle-Tacoma International Airport over the past year, going head to head with dominant local carrier Alaska Airlines.
United s McCarthy said the airline now has a reduced domestic and international schedule out of Sea-Tac compared to recent years, but added that we re not announcing any changes to our flights going forward.
