Give yourself 4-5 hours of wiggle room because this route is frequently understaffed and the gates are far enough apart to make 1 hour very difficult if any issue should occur such as staffing or weather delays. As soon as a flight boards the airline staff are MiA.

security access line for Premier access was very reasonable, process was less than 10-15 minutes. Leave time for dropping off a rental car - is a bit of a walk and then AirTrain transfer due to the current construction - so allow time for less stress. take advantage of the tables in the boarding area for charging devices or doing work.

Airline reviews

I was very surprised that at the Seattle airport, Alaska's main hub, that the gates were very small and very close together, and it was very hard to discourage between my flight, and the flight next to us going to Boise and the flight next to that going to Denver. Denver. The audio for all three Gates was at the same level, and almost impossible to differentiate unless they actually said their flight number and location. Location. People tried to get on our plane, before they were ready, because they were confused about the Denver announcements. We were on a Boeing 737- 800 00, that must have recently been redone. It actually had USB--c ports which really surprised me. The Apu was out on the plane, so when we got on it was very very hot. A lot of people were complaining. The gate agents were very professional, but it was a lot going on and even though there were two of them, I think they could have used another person to help them. Mandy was particularly helpful in getting me a window seat. Flight crew was up to the usual Alaska airline standard, which is very high. Can we please get another snack then garlic pretzels? It would also be nice, if they knew ahead that the flight was full, to offer to let us check in our bags for free at baggage check, and not at the gate!

Very terrible/ never will I fly this airline again. Poor service in the plane. They cancelled a flight without booking another. All the way around it was too awful.

Terrible experience with an extremely obese passenger seated directly behind me - who snored and gagged so loudly, even throughout takeoff, that no one within ten rows could have gotten any rest even with earplugs! I get that this poor person has a serious health issue, and that Alaska (maybe) had no way to prepare in advance (though he did occupy two seats). Still there must be a way to take a six-hour flight without feeling like I'm next to a roaring grizzly bear.

It might not have been their fault, but there was a two hour delay due to weather. Then we boarded and were about to leave when they said there were more problems at the destination, took us back to the gate where we had to fully deplane. But then five minutes later, they said everything was fine and to get back on the plane. This was the part that pissed everybody off.

No healthy food choices. There was no in flight entertainment .

The check-in crew for Alaska was rude, unhelpful, and the opposite of customer-centric. We arrived 50 minutes before our flight and were told it was too late to check baggage. When I asked what the cutoff was, the agent started speaking in codes “D50” and yelling to their manager who also spoke in codes. They then tried to speak to me using these codes and all I wanted to know was the time of the cutoff, which they would not — or could not — articulate. They booked me and my family on the next flight while smirking.

Generally Good. Outbound flight was marred by a continuously s creaming baby. Fortunately the flight was only 90 mins long it would be nice if people traveling with small childres could be centered in one part of the plane. Also, you need to adapt your servey to include a "not applicable " option for things like food and entertainment, which are not offered on shorter flights. I fily Alaska by choice as given all the cirumstances, I fel\el you do a good job.

i canceled my flight from SEA to SFO, SNA to SEA and received full refund from Alaska Airlines. i am pleased with the customer service.

i canceled my return flight package with Alaska Airlines. Customer Service was excellent and assisted me to cancelled both of our reservations and returned the payment in full. that is excellent service and understanding and empathy of the customers' needs. i like Alaska Airlines and recommend AS to everyone.

Representatives both at the gate and on the plane have zero interest in helping you! It’s really unfortunate…

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

Everything went smoothly, although the usual gripes about airline travel were still present: the boarding process is inefficient, the snack selection is limited, and so on. Since there was extra space on the flight, the gate agent rearranged many people's seats to put people on the aisles and windows, leaving the middle seats empty, as much as possible, which was pretty great.

One of the flight attendants was a little cranky. I appreciated the free wifi and plug to charge my laptop

WiFi didn’t work most of the time. The usb chargers would work only occasionally for 5 mins and wouldn’t charge after that. Had to keep trying repeatedly at each of the seats in the row.

Generally on time departures and arrivals, clean planes, sky miles membership provides great benefits (complimentary upgrades, etc).

my mom urmila patel needed a wheelchair which was not available on the curbside. she needed to walk almost 50 meters inside (at the risk of falling) and then had to wait in line to get a wheelchair (this is not ok). Once obtained she had to seat in it for 30-45 minutes for someone to take her in thru the checkin process (which was fairly smooth and easy). the lady who helped her with her checkin process was very courteous and helpful

Awful - both legs. The check in was awful, getting on the plane required walking down a spiral staircase (dangerous), then taking a bus about 5 miles out from the terminal. The seat was broken (I was in business), there was no internet during the flight (both legs). The aircraft was very old. I saw rust in some place, tape holding things up in the bathroom. This was an unacceptable experience for such a long haul flight.

I usually get upgraded so my experience is usually amazing. I did not get upgraded this time - which was fine - but the wifi had issues, the monitors were going in & out, & (though not Delta's fault) one of the gentlemen next to me desperately needed a shower.

I really liked the legroom. I am 6’4”.a at For some reason our seats were not together and using the app to fix it didn’t work. Passengers were nice enough to move for us but you should absolutely ensure a parent sits with their child.

Staff were friendly and happy. Delta could make sure passengers that don't have the app know of changes. Without Kayak I would not have known about the change of gate or the delay. Kayak was faster to notify me.

United has been holding my money for a cancel on another ticket they wouldn’t let me fly for going on 5 months. Terrible service I wouldn’t choose to buy tickets or fly with united again. Very bad experience generally dishonorable and poor service .

The flight got delayed. They forgot to bring the drinks when I asked for it. The toilet is messy.

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

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.

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Crew was great! Good meals. Had room to stretch out

How can you rate a flight when it is canceled after you leave the gate & 3 hours into sitting there or in remote area of airport after mechanical problems

Seat pitch is horrible especially on the 15 hour flight. Gate crew at SFO was Outstanding. The flight crew was also great.

6 1/2 hours from Tampa to SFO on a Boeing 737. Cramped. No Service. No real food. One pass for coffee at the beginning and a second pass THREE hours later. And check-in in Tampa was nasty even by United standards. And I am at almost TWO million miles on United. It's a non-stop. But terrible service.

First class ticket gets you no seat back entertainment? I have to bring my own laptop to see a movie? And most of their movies have ADS? No thank you. Worse: Tiny snacks only on a 2 hr flight?

The flight attendant was very polite and attentive. The food was good.

I had a comfortable and enjoyable experience. The entertainment options were plentiful, the food was appetizing, the snacks were tasty, and the staff was friendly, professional, and helpful.

Was put into a seat right behind the toilet that had no entertainment possible but did have plenty of leg room over noisy part of plane.

Flight: Started on time. Comfortable flight. Arrived on time. Crew: Very cordial and helpful. Drinks and snack was served with a smile. Overall enjoyed the trip. Regards, Hari Doss Chanchala Doss

Buying ticket from kayak instant booking was a huge mistake, never to be repeated again! The Kayak didn’t book the tickets directly, it handed it off to a third party Underpricer, that booked a code shared American Airlines flight operated by Cathay Pacific!! When managing the booking American Airlines would recognize the itinerary but wouldn’t let me do anything stating, the flight is operated by Cathay Pacific so go to their website. Cathay Pacific would recognize the itinerary, neither by reservation ID or ticket number…asking to reach out to the third party Underpricer….calling Underpricer resulted in no help like seat requests, mileage number or upgrade request, 15hr layover accommodation voucher guidance…so net in net avoid booking through three layers of intermediaries

A first class seat should fit a fat person, and this doesn't. The trays in the armrest are less functional than an ordinary tray in the back of the seat.

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

I flew Business Class. Rory, one of the Cabin stewards, was attentive, explained the menu, provided appropriate drinks. was

This was a horrible experience. For a first class experience, my chair was held together by 3M tape - and I have a photo. The crew weren’t very attentive, somewhat dismissive and forgot my drink and snack, the chair reclined about 3 inches on a 6-hour cross country flight. I was also not informed that there was no lounge available in Newark airport because of renovations, so all around this was one of the worst experiences and I would actively avoid both American and Alaska Air going forward.

Long 5 hour and 45 min flight and only one drink service and cookie snack

Charges unexpected. For seat that didnt recline. Please reverse extra seat and carryon charge. Bad business that is a bait and switch.

I couldn’t check in because the app didn’t work. It took 3 Frontier employees at the counter to get me checked in. Flight left 3 hours after departure time

Horrible! The short distance flight ended up taking 5 hrs! There was a 3 hr delay for the flight to take off and there was a 70 min wait on the tarmac for some bogus reason that the pilot said the gate he was supposed to board was taken up. After a 30 min wait he said the plane that was supposed to push out of the gate called a medical emergency and 40 min later he ended up boarding another gate. For the initial 3 hr delay there was no information/alert about the gate or delay in the app or the boards up until the boarding time and even beyond! Had to walk all the way to the end of the terminal to find the frontier staff to ask what was going on. Avoid this airline at all costs! If you have carryon bags or checked bags , their prices come equivalent to the prices of more reliable airlines. They are the worst in timeliness at 60% (reported as delayed) this year (check the data) by a high margin even compared to the second worst airline. If you are ok with having a miserable flight experience with the odds close to flip of a coin, feel free to try them. If you value your time , money and flying experience, stay away.

Our flight was delayed by four hours without notice, the app for getting my boarding pass is super confusing, and I wasn’t able to check a suitcase without paying for a higher cost package

First the gate was a total nightmare-no chairs anywhere! So over crowded and only one bathroom and nightmare of food service - took forever and NOT one place to sit. No inflight entertainment and had to pay 60.00 for a small carry on. I will never fly Frontier again!

Flight was 3 hours late leaving. Poor communication from the staff about delays. Impossible to get in touch with customer service (by design). And it actually didn't come out to be much cheaper than a non-budget airline! Not worth the headache, I'm never flying Frontier again

See my previous comment which is mostly about our flight from Phoenix to SFO

The check in at the airport was awful. Told I need to pay for a bag. The item was taken at screening. I went back to get my $ back and they gave me a coupon with a QR code that doesn’t work. Worst costumer service ever!!!!!

4 hour delay because they used our aircraft to fly a different segment (per the captain)

absolutely horrific. delayed flights, overbooking. over charging. nightmare service beyond words. stay away.
