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.

Almost 3 hr delay in Settle with very little information available to passengers. They boarded the plane and we waited for a long time inside the plane as well.

Almost 3 hr delay in Settle with very little information available to passengers. They boarded the plane and we waited for a long time inside the plane as well.

The flight was fine, but the Kayak app is terrible. I could not input my flight. I couldn’t use it for anything and it would not even let me try to add a seat once you purchased the ticket you might as well. Delete the Kayak app as far as I’m concerned. I’m done with kayak. Com

Food and entertainment not applicable - standard drinks and cinnamon cookies; crew did not do a song and dance for us so no entertainment. I like the slightly better leg room than American Airlines - at least it felt that way. Flight crew and atmosphere seemed more welcoming than American, too.

It was fine, mostly I was just happy to be on my last leg home. No in flight entertainment but that's forgivable since it was only a 2 hour flight.

Flight was cancelled, then rebooked on a flight that I was unable to get through since they had closed the gate.

Alaska Airlines adds time to flight time to make up for late departures. Also Alaska Airlines destroyed my suitcase and I had to buy another suitcase for return flight. Very frustrating and not sure I would fly Alaska Airlines again.

Landed and parked in back of larger jet. Cabin filled with jet exhaust. Left many with headache. I got sick to my stomach. Scrambled to find airsick bags

Plane seats are comfortable and seemed more roomy than others I have been on. Playing was clean and flight crew friendly. Passengers who have a connecting flight should however be allowed off the plane first

flights on time, flights that were leaving when scheduled..having the alaska people on the phone and most of all getting rid of the new atmos website it is terrible!!!!!!!!

Only issue was at the gate the clerk tried to get us to check our carry on bags. When I questioned the other clerk said, the flight isn't full, they are fine to carry on
