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 
MarisaFlew with American AirlinesSEA-LAXJun 2025
Take Alaska Airlines - Clear was great to have at both airports, especially seattle where there was a large security line
ReidFlew with United AirlinesSEA-LAXOct 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 AirlinesSEA-LAXNov 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 AirlinesSEA-LAXJul 2024
LAX is a bit of a mess. Very long walk between terminals.
LaurenFlew with DeltaSEA-LAXFeb 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.

Original flight was canceled, and the automatically booked second flight was immediately delayed. I arrived about 4 hours later than planned with only a $12 meal voucher that didn't fully cover a sandwich at airport prices.

Original flight was canceled, and the automatically booked second flight was immediately delayed. I arrived about 4 hours later than planned with only a $12 meal voucher that didn't fully cover a sandwich at airport prices.

It was very good and comfortable, Crew was also great

Good experience, although it was a little cramped being a tall person. Otherwise everything went smoothly and professionally though

Delay of more than 3 hours I didnt recieve neither a voucher for food Attention disaster

Flight was very warm. It felt like there was no working AC.

Passengers were not informed timely of delays. The staff appeared like they didn't really care about the passengers.

Both flights were delayed going to our destination and leaving, and communication about the delays was not great by the airlines, now the crews were phenomenal and great to be around!!

Delayed. It's not our first flight with them either, it's actually our 3rd and all 3 were delayed by hours each time. It was a myriad of delays. On one flight we boarded after being delayed for a little over an hr, only to be told we were going to sit in the plane for another hour before departing. Once landed, we waited another 40ish min to get to our gate. On another flight, flight was delayed just under 3 hrs but atleast we got to wait it out at the airport terminal. Its just a bad experience overall flying with Alaska Airlines.

It is very bad they do not give you money back

The only problem was the time delay. Kudos to the counter agent in Seattle. Very helpful and gracious.
