Insights shared by verified travellers who flew the route from Seattle to California 
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
Verified travelerFlew with Hawaiian AirlinesSEA-ONTJun 2025
Make sure to be there on time because the bag drop off can be a little complicated and it takes quite some time to get to the gate.
ShuraFlew with Alaska AirlinesSEA-BURApr 2025
Don’t . Delta has all the gates together for easy transfers and much more food and beverage selection
RobertFlew with United AirlinesSEA-SFOMar 2025
If you’re picking up a rental car it’s not very clear that you have to take the train. Signage can be improved at SFO.
Verified travelerFlew with Alaska AirlinesSEA-PSPDec 2024
Be courteous of your fellow travelers. Remember the carry on baggage rules. Keep your jackets out of the storage bin on full flights. Don't move other people's luggage from one bin to another. Step out of the isle as quickly as you can. Be sure you're in the seat(s) assigned to you.
Verified travelerFlew with Alaska AirlinesSEA-ONTOct 2024
SeaTac lets you make an appointment to get through security. SpotSaver. No cost. Online.
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.
KimberlyFlew with Alaska AirlinesSEA-SNAJul 2024
When going to Disneyland fly to this airport. Only 8 miles from Disneyland and super quick to check in and check out. Highly recommend this airport!
Verified travelerFlew with Alaska AirlinesSEA-BURAug 2024
Burbank Airport is the best place to start your travels: small airport, short lines, and easy check in.
Verified travelerFlew with Alaska AirlinesSEA-SJCAug 2024
The airport is busy and a mess with construction. There is a train to take so account for extra time.
Verified travelerFlew with Alaska AirlinesSEA-SNAAug 2024
Flight was delayed 9-1/2 hours. Make sure you have somewhere to go in you have to check out of your hotel.
LauraFlew with Alaska AirlinesSEA-LAXJul 2024
LAX is a bit of a mess. Very long walk between terminals.
Verified travelerFlew with Alaska AirlinesSEA-FATMar 2024
Enjoy the flight. You can see Yosemite national park half dome and el capitan from left side window seat
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.

Airline reviews

I was in the middle seat in the last row but that wasn’t their fault. It is why I rated the flight as mediocre, also the landing was a little rough. The good was really good. The self service luggage belt at SEATAC stopped working right when I reached it. I was literally placing my bag on the small belt when the main belt stopped. I understand that it wasn’t just Alaska but the entire side of the terminal. It took the agents about 20 minutes to arrive at a game plan and it certainly wasn’t flawless but they arranged for our luggage to be taken to the plane the old fashioned way by hand. Understandably, the plane was late in leaving. The flight took the proper amount of time and instead of arriving at OAK at 1:45, we got there at 2:30. I took my time getting to baggage claim because I knew it would be late if it was there at all. Sure enough it wasn’t but there was an agent there to greet me and inform me about my luggage. Long story longer, they delivered my luggage to where I was staying which was an hour away from the airport. Alaska has instituted a delivery type tracking system through my email that kept me informed of where my luggage was the whole time. WELL DONE!!

I am always uncomfortable about the boarding process. I think every airlines has their own procedures for boarding but all of their procedures are inconvenient because it takes too much time to board. If you board people from back seat to front, I think you can reduce the time to boarding.

There was a delay, then we were boarded, then deboarded, then waited another hour for a new flight, then boarded again and arrived 2 hours later than expected while traveling with 3 young children.

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!!
