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 
Verified travelerFlew with Qantas AirwaysSEA-LAXNov 2024
Alaska and Delta by far have the best service from Seattle to LA, with many flights a day. I honestly prefer Alaska in general, but they codeshare so much with American, whom I generally loathe, that I have been switching my flying to Delta simply to avoid American. American themselves run 2 CRJs a day via SkyWest to LA, and United runs one or two flights as well. The American service is what it is — I only took it due to a vastly lower price for a Qantas ticket to Australia.
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.

Flight was over an hour late, and we got notified every 15 minutes, beginning right at boarding, that it would only be 15 more minutes until we finally left about 75 minutes late. Of course, no compensation was offered.

I needed to board early and that was no problem. The snack was just ok. Alaska is an EXCELLENT airlines . . . luggage fast and easy.

Alaska Airlines needs more bag tag kiosks and bag check-in stations in Seattle. A single entry point for the bag tag kiosks would be helpful. This alleviates lines forming at each individual kiosk, which causes traffic jams for people passing through.

It was raining and cold and we had to walk outside to board the plane. And to have yo stand outside to wait in line to board. It seems they could find another way to send a few people at a time so passengers are not outside in the elements. Then to not have my luggage show up at my finally destination. Not happy with the whole experience.

THere was no WiFi and therefore no entertainment on the flight, but everything else was fine. The flight got in so early we had to wait for a gate to be clear.

I paid $49 to select my seat---6A a window seat just behind first class. When I started to get on the plane I was told that my seat had been given to someone else and I now had a middle seat. They finally gave me an aisle seat. When I told them I wanted my $49 back, I was told I would need to call alaska and fight with them to get my money back. And when i was on the flight people going by kept hitting me with their bags. I have tried calling alaska twice to talk about a refund but never got thru to the right person!

Check-in was easy, I did it from the app. Boarding was easy, the crew was great. Santa Barbara airport had a disabled plane so we had to land in Burbank to refuel. They kept us well informed, and everyone was great. A very entertaining person from the Burbank airport got on and told a few jokes.

It went very quickly even though we were late in leaving Fresno.

Like I said before the internet was shut off so there was little to do on this leg of the flight.

Finally get a snack n drinks! Just like the good ole days!
