Frequently asked questions

Is it cheaper to buy a plane ticket from Sea-Tac Airport to WAG last minute?
Being the spontaneous type is a terrific way to explore the globe, but it's not necessarily the best method to score a bargain flight. Consider booking your Sea-Tac Airport to WAG trip in advance instead of leaving it to the last minute. Based on flight pricing and demand studies in 2022, we have found that the best time to book domestic flights is between 28 – 35 days ahead of the departure date, and international flights three to four months in advance. Save all that spontaneity for when you reach WAG!
