Planning Seattle to Los Angeles? Work through this
Before you book
✓Compare the whole ticket, not the fare. Spirit Airlines, American Airlines and Southwest Airlines fly this route, and their bag and seat fees are all different — the cheapest headline is rarely the cheapest trip. Our airline guides show what each one charges.
✓Book in the window. For a 960-mile trip, booking 3–6 weeks ahead is the sweet spot. The final two weeks are when prices step up, so if a fare works, take it — or set a fare alert on this page and let us watch it.
✓Check both directions. The return fare doesn't have to mirror the outbound one — mixing departure days often beats a tidy-looking round trip.
On the day
✓Leave early. Two hours at SEA is the plan; ninety minutes is the gamble. The flight is 2h 27m nonstop — your ground time either end will likely beat that.
✓Carry-on if you can. Skipping bag drop saves twenty minutes and one line on each side of the trip.
✓Download before you board. Entertainment, boarding pass, and your ride from LAX — sorted while you still have signal.
