Flights from Seattle to Los Angeles: the best tips from KAYAK users' own experiences

Insights shared by verified travellers who flew the route from Seattle to Los Angeles 
LindaFlew with Alaska Airlines-June 2026
Once you’re past security, you have to take the tram to your gate area. It’s quick and easy.
MarisaFlew with American Airlines-June 2025
Take Alaska Airlines - Clear was great to have at both airports, especially seattle where there was a large security line
ReidFlew with United Airlines-Oct 2024
SeaTac does not have a very good or equitable system for security lines. First class passengers don’t have a TSA precheck option, while there are only 2 TSA precheck lines on opposite sides of the terminal. Highly recommend getting TSA plus Clear, as the airport heavily favors this combination, with each section of the terminal having one of these options. I almost missed my flight because the only TSA precheck line was about 45 minutes long.
BruceFlew with Alaska Airlines-Nov 2024
Tight interline connection at LAX - barely made the flight. Directions from AS arrival gate to separate AA commuter terminal for AS codeshare flight connecting to TUS would have been nice.
LauraFlew with Alaska Airlines-July 2024
LAX is a bit of a mess. Very long walk between terminals.
LaurenFlew with Delta-Feb 2024
If you have kids, bring your own screens. We were counting on the inflight entertainment and it was a definite letdown. Also, TSA Pre-check is only available at station 2, but wait times are posted at each station so you can see if it’s worth the walk.
