Flight deals from Los Angeles to Seattle

Departures for this route are searched from Los Angeles International (LAX), with Seattle-Tacoma International (SEA) as the destination. Burbank (BUR), Long Beach (LGB) and Paine Field (PAE), north of Seattle, are not part of this search, so the code on each result matters. Delta, United, American, Frontier and Southwest have appeared in EazAir's fare checks for this route. Sea-Tac's train guide places Delta and United at the S and A gates.

FlyAway buses run to the LAX terminals from Union Station and Van Nuys, 7 days a week, and ride apps can drop you right at your terminal on the upper Departures level. Drivers should expect nightly lane restrictions on westbound Century Boulevard until 13 Nov 2026. LAWA has also warned of detours and longer shuttle times from construction, and it suggested TSA PreCheck and Global Entry for quicker screening. Delta checks in at Terminal 3, with gates there or in Terminal 2.

Sea-Tac's six concourses sit in one terminal. If you land at an S gate, the SEA Underground Blue Line carries you to the B and A concourses, and the Green Line links N, C and D. The free Train-to-Plane shuttle connects the terminal and the Link light rail station from 5 a.m. to midnight, seven days a week. Taxis on the 3rd floor of the garage come in two kinds: flat-rate cars have four-digit numbers and two colors, metered cars three-digit numbers and one color.

From 28 Sep to 14 Oct 2026, EazAir ran its first 5 fare checks for LAX to SEA, each for the lowest one-way economy fare for one adult with departure 30 days out. The highest of those results was at least one and a half times the lowest, which came on 6 Oct. Delta says its Main Basic fare includes one carry-on and one personal item free.

Travel tips

Arrive early for domestic flights

TSA generally recommends arriving at least 2 hours before a domestic departure, more at larger hub airports during peak travel periods.

Pack a mixed carry-on

Keep a change of clothes, chargers, and any essentials in your carry-on rather than only your checked bag, in case of a delay or a bag that doesn't arrive with you.

Screenshot your confirmation

Save a screenshot or PDF of your booking confirmation and boarding pass before you travel, in case you lose signal or battery at the airport.

Check in online when it opens

Most airlines open online check-in 24 hours before departure. Checking in early can help with seat selection and, on some airlines, boarding group assignment.
