Insights shared by verified travellers who flew the route from Seattle to California 
Verified travelerFlew with Alaska Airlines-Oct 2026
Smooth transition, bit of walking from baggage claim to customs to trains for gates. However, very quick at quiet times, loved it. No issues, had a coffee along the way.
Verified travelerFlew with Alaska Airlines-Oct 2026
Seattle is a large, confusing, multi gate airport. Various modes of access to gates is not always clear. Prepare for delayed flights as flight turnovers are high.
Verified travelerFlew with Alaska Airlines-Oct 2026
Make sure you bring a fillable water bottle as often turbulence makes in flight drinks or snacks unlikely. Plan on delays and don’t expect any kind of exemplary service. I would love to say it’s a fluke but my last 4 flights have been the same. Mediocre to worse is about all you can expect.
LindaFlew with Alaska Airlines-Jun 2026
Once you’re past security, you have to take the tram to your gate area. It’s quick and easy.
Verified travelerFlew with Alaska Airlines-Jul 2026
Super easy to park in the Economy Lot #1 and take the shuttle to the terminal.
GeraldFlew with Delta-Mar 2026
Flights earlier in the day are better - less chance of stacking delays. Much better than SFO flights, They're terrible in August (fog).
ChristineFlew with Hawaiian Airlines-Dec 2025
Arrive early to go through security unless you have TSA pre check and/or CLEAR
MarisaFlew with American Airlines-Jun 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 Airlines-Jun 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 Airlines-Apr 2025
Don’t . Delta has all the gates together for easy transfers and much more food and beverage selection
RobertFlew with United Airlines-Mar 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 Airlines-Dec 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 Airlines-Oct 2024
SeaTac lets you make an appointment to get through security. SpotSaver. No cost. Online.
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.
KimberlyFlew with Alaska Airlines-Jul 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 Airlines-Aug 2024
Burbank Airport is the best place to start your travels: small airport, short lines, and easy check in.
Verified travelerFlew with Alaska Airlines-Aug 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 Airlines-Aug 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 Airlines-Jul 2024
LAX is a bit of a mess. Very long walk between terminals.
Verified travelerFlew with Alaska Airlines-Mar 2024
Enjoy the flight. You can see Yosemite national park half dome and el capitan from left side window seat
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.

Delays. Again. Haven’t had a good experience out of Seattle in most flights. The flight was delayed and passengers were all bunched in one area even after the doors closed when there were tons of empty seats. Attendants chastised passengers for wanting to move and even embarrassed one man for telling him tons of the empty seats were actually premium seating and he needed to go back to the back of the plane the seats have been getting increasingly uncomfortable and the snacks are terrible if you get one. No options for people who don’t/can’t eat sweets. Prices keep going up and amenities and service keep dropping. Air travel has become more like taking a very expensive bus.

As a deaf person I appreciate the assistance provided by the boarding staff and the flight attendants.

Good seating and leg room. Able to choose seat. Nice crew, polite and helpful. Nice snacks. Meals have to be pre ordered, short flight do no meal required.

The flight attendants stood there talking to each other instead of welcoming people on the flight.

Truly, everything was professional, and extremely friendly with lots of smiles from all the staff. My only complaint is that both coming and going from San Francisco to Seattle and back the public announcement system on the airplane when I was sitting in the exit row was so loud that it hurt my ears, and I was not the only one I did report it to one of the stewardesses who thanked me and apologized, but truly Alaska Airlines is my favorite domestic Airlines by a far shot

Alaska did a great job of accommodating my needs and treating me fairly. I appreciate their willingness to smile and be caring.

It was a good experience because it was unremarkable. The exception was we were an hour delayed.

Staff friendly. Impressed that she spray cleaned the seat when I voluntarily moved to another before take-off.

Plane late by an hour. Would be nice if it is on time

Pretty good flight. Airport lounge was dirty, crowded, and noisy.

dropped my bags at Seattle Delta curbside. 1.5 hours before departure. one bag oversized made it. the other was left at curb and mishandled. poor communication from delta in sjc baggage claim. No internet on flight and food choices in business are horrible. You are forcing us to fly Alaska which is shockingly better than the Delta experience. that is a low bar.

Comfortable seats. Nice service online. Short flight, so not a lot of time to enjoy.

The flight was done by SkyWest only WIFI no entertainment center are available on the CRJ

Love me some Delta. One of the few airlines to recognize and support veterans. Easy boarding, flight was on time and arrived early and the flight attendants were excellent on this flight.

We sat on the runway for over an hour before departure. That was unwelcome.

The cabin temperature was nice and cool. The wifi was not working.

Was forced to check in my small carry on, even though I informed the crew it has very fragile items inside

Food was surprisingly good but the WiFi was not great

The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.

Had a broken tray in business class. Crew just shrugged it off.

Seats were new and comfortable. Staff was fine. Missed my connection due to weather -which wasn’t their fault- but got no help at all. Gate staff sent me to customer service, which was and stayed unstaffed. Sign with QR code directed me to call or chat. Chat was useless. Call was returned after an hour. No itinerary offered by Frontier could get me home in less than 30 hours. Rebooked with another airline and got a partial refund that came to about 10 percent of what I paid to get home.

As every law enforcement agency I could imagine surrounded the plane and we didn’t disembark for 2 hours and then had to stick around for another hour to go get our personal belongings after leaving them behind and being bused away from the plane, it was scary and inconvenient. We were given no information as to why this was happening. Lack of communication with passengers was disappointing.

The ticketing agents were rude but then we had a great gate agent very nice we had to ride a buss out to where the plane was parked but it was in some back corner of the airport when we got to the plane the captain who was great btw was cleaning the plane because the same rude ticketing agent told them they we not contracted to vacuum the plane. The ride to las Vegas was fine We had a connecting flight to Dallas. The flight was fine but when we arrived in Dallas everyone who flew on any frontier airlines the picked up bags from baggage claim D15 had to wait over a hour for their bags to start we arrived at 11:30pm ish to the gate we didn't leave the baggage clamed till 12:50 am very not happy and i used to fly frontier 4 times a week for work in Denver i will not be using them again

Terrible communication with weather delay, lost baggage, near impossible to reach customer service

The crew was mostly okay. The flight attendant who answered our questions was curt and unhelpful unfortunately. He seemed upset and I understand having off days.

Flight was delayed one hour. Notification to the crowd waiting near the gate was terrible…announcements were unclear and very hard to hear and therefore understand. Frontier does NOT send texts to notify, only email. The reader board over the gate itself was NEVER updated to indicate the gate had been changed. It’s like a bunch of children are running things.

We’ve all seen the YouTube vids of out of control passengers. But this was an instance of a highly aggressive, bully flight attendant. Yelling in the face of a vet with PTSD who was texting their family. And no , we had not yet been instructed to put our phones in airplane mode. My suggestion is that you should pay whatever difference there is in order to avoid Frontier airlines. Additionally, after 3hrs trying to get customer service frontier offered a $25 voucher. I declined. This experience was so traumatic. To be verbally assaulted and abused by a flight attendant that has the power to say “boo” and I miss my flight ( which was to a family member’s funeral ). Frontier is unsafe and I cannot impress enough how much I discourage anyone ( esp those with any kind of disability like PTSD ) flying on Frontier.

We had to wait in line over an hour just to check our bags. It's a good thing we were so early to the airport. Only one clerk was working and the line was around the corner and down the hall. No good. I felt bad for her. Not sure how she kept her sanity with all the upset people. Then we get to our gate and there is no seating. Everyone was standing. Then I realize it is not a gate at all, we still have to be shuttled to our airplane. Ugh. Then we were late taking off and missed a window of opportunity before the airport runways were shut down for some reason. (not frontier's fault the runway shut down.) The seats on the airline are crammed and there is no cushion. Never had a tighter seating arrangement while flying. My 6' 4" husband was absolutely miserable the whole time with knees digging in to the seat in front of him. You think you are getting a good deal on a ticket, and then wham! I had to pay 75 dollars for our checked bags and 75 dollars for a carry on. No other airline does that!!! And also, there is a 40 pound weight limit on checked bags... Would have been cheaper flying with another airline, and I would have at least gotten a snack and drink. Was thankful for the tiny cup of water at least.

I was surprised that all baggage, including carry on, were charged. Each additional bag went up in cost. Really disappointed in the additional costs.

The agent at check-in was strident, unwelcoming, and condescending to customers ahead of me.
