01 / OVERVIEW

Booking tips for SeattleDetroit

For most economy fares on Seattle to Detroit, booking roughly three to eight weeks ahead tends to hit the sweet spot on price, with last-minute fares rising sharply in the final two weeks. Tuesday, Wednesday, and Saturday departures are usually cheaper than Fridays and Sundays, and early-morning or late-evening flights often undercut midday slots. If you are traveling light, the difference between a basic economy fare with carry-on only and a standard fare with a checked bag can be significant. Compare both options before booking, and also check whether SEA or DTW has a nearby alternative airport that might offer better fares on the same dates.
