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).
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-Aug 2024
The airport is busy and a mess with construction. There is a train to take so account for extra time.

Terrible delay today. also, waited 90 minutes for baggage to unload in Seattle earlier in the week.

Seated at front bulkhead for a smidge extra leg room away from home and on flight back home. Away crew was very proactive about assuring our carryons had space close behind us (because no seat in front of us our personal items had to be in a small bin overhead). They actively required passengers place overhead luggage on its side so more items could fit in bins. Home crew made no such efforts. I had to struggle back rows to get overhead bags upon landing, no crew help then either, and some disgruntled passengers as I and others retrieved our bags. There was a system that worked pretty well. The home bound crew just didn't feel like working.

Flight left on time and was early landing. Seats not comfortable and not enough space…

It would have been better if the flight was on time

Not having a five hour delay with little notice! The crew was very kind, though, and just as tired as we passengers were. The flight didn't depart until nearly 1 am...and no reason was ever given.

Great flight from Seattle to Phoenix and to Chicago-Midway from Phoenix

Very smooth checking in our luggage with a super pleasant SW agent. I enjoyed a fun entertaining movie.

I really like open seating. I hate that I've heard this is going away. This is one of the unique things that makes Southwest my goto choice.

The people of SW Airlines really make it nice to fly.

More assistance and clarity for travelers with gate checking and lap children

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.

My trip was delayed by more than two hours and missed my connecting flight to Fiji due to delayed they have to change my flight to United Airlines and stranded in San Francisco for 24 hours waiting for United next flight after almost 3 days I finally arrived in Brisbane airport but my luggage wasn’t here and now I still don’t have my luggage and still without my clothes and my needs. The first full day of my vacation is horrible because I don’t have any clothes and still trying to contact airline for luggage update and hopefully they will tell me the truth instead of misleading me and I end up waiting around without enjoying my vacation time here in Brisbane.

I was offered a selection of drinks and given a free snack. The flight was only a couple of hours, but we were trreated better than the transatlantic flight.

Hate the way they nickel and dime you on pricing. Extra for baggage, extra for a pre assigned seat. Make it one price and be done with it.

The flight got delayed for some unknown reason to us. Then, after boarding, we stayed grounded for almost an hour without any explanation or announcement. Then, finally lifted off. When we landed and made our way to baggage claim. The luggage took 30 minutes to come! It was past midnight due to the flight being delayed and my litter children were cranky and tired! It was not a great experience. Perhaps, more explanation of what is going on with the flight would be helpful!

Good flight, loved the snacks (Biscoff cookies). For boarding, they forgot to change the sign showing our group was boarding. Apparently, they had announced it, but the announcements overlapped with another gate announcements and no one could actually hear what they were saying. So a group of us were waiting....and finally asked and were told we could board.

overall no call for accessible while boarding. The crew member was little rude not bothering about the condition. Seat assigned was very uncomfortable.

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.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

The crew at Hawaiian Airlines was fantastic. Kind and hard working. The pilots were great with giving us all the updates to make sure we were informed.

We got surprised and switched to Alaska airline. Dirtiest tray and seats I have ever board on and we travel all the time. Help desk would not help by chat as I'm disabled to get my sets assigned tell me call Hawaiian air. I call Hawaiian air was told the flights RT are by Alaska. Make it short, worse flights of our life.

First class ticket. They ran out of food and I sat hungry watching the others eat

My experience was pleasant. It was perfect. That is enough🥰💃💖

I could not check in ahead of time. Kayak did not give me a proper confirmation number to check in.

It was not a good experience. When I went to check-in one of Alaska's employees told me I had to check-in with Hawaiian Airlines, which was on the opposite side of the airport. I made my way over and when I got to Hawaiian Airlines they told me I was in the wrong place. The employee saw the look of defeat in my face and was able to get someone to check me in and text me my boarding pass. I had to make my way all the way back to the other side of the airport and barely made my flight. I think it would be very helpful for employees to be more informed with these Hawaiian flights that are operated by Alaska so they are not rerouting people to the wrong terminals. Also, clear signage in the check-in area.

The ticket and bag check in was chaotic at SEATAC. No clear communication or signage for bag drop off.

Hawaiian and Alaska are at opposite ends of the Seattle airport. Apparently, during this time of transition through their merger, only people flying to Hawaii should go to the Hawaiian desk. So, I had to carry my luggage the entire length of the airport. Alaska's desks were sort of a temporary set up behind a wall, and even after all this, they (Alaska) had a great deal of difficulty confirming that I was on the flight, or that I had paid my checked bag fee. Now, they did try to compensate for all this confusion. There was an impressive number of agents, actively engaging and working with customers - not just standing behind the counter, but going out to them with pads in hand. It took some time, but I was squared away, and was apparently upgraded to a business class seat with lots of legroom (much appreciated). I was told this transition would last till August.

I'm was impressed with their service. Everything was great

Hawaiin airlines never let me know the alaska airlines confirmation number. it took chat and call with customer service to get that.

Flight be on time would be a good start. Then train your flight attendants to be attentive and friendly. This time they completely forgot my row for the measly snack! United, do better!

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Delayed by 2.5hrs any longer and they would’ve had to honour their own policy for breaking their own rules and regs. Not cool, especially when I have an infant child that needs to stay on a routine and they get schedules.

They had three choices for snacks - but you could only have one - and they ran out of the dark chocolate before they made it all the way down the aisle... Packed flight - limited service.

They opened my checked bag and even though my lock was tsa approved, they loose my lock and left my bag just like that. Incompetent people, very upset about it. I’ll try to avoid traveling with united

We fly to Ecuador frequently. Checking in is usually a hassle because most United agents take some time before they can verify that my passport doesn't require a visa to Ecuador. This time the process was even longer due to the cyber attack. But she was really nice to us. So glad we brought plenty of snacks to supplement the 3 flights from SEA to GYE.

The weather caused a delayed but I was impressed how United did everything they could to try to get us out which included bussing us to the plane doing a Hardstand and bringing us to the plane since the fog was too thick to tow the plane from the overnight stay in the cargo area.

Food was really good. Chicken curry delicious. Great service. Had 3 seats, what a pleasure. What about a healthier desert option on the dinner? Yogurt, fruit? Thankyou
