Our gate agent was absolutely amazing. Personable, kind, and helpful. She alone makes me want to return to use Alaska Airlines.

Our gate agent was absolutely amazing. Personable, kind, and helpful. She alone makes me want to return to use Alaska Airlines.

Don’t fly with Alaska if you have a layover in Seattle. Guaranteed to screw you over. We waited at terminal S3 &were >2 hours delayed(mechanical issues)and told to change terminals to a different plane that required riding 3 shuttles to get to new terminal N14. Then they delayed the flight even further and changed gates again. when I went to the customer service in terminal N, the manager turned me away without apologizing & refused to assist me but mandated I leave her alone as her shift is nearly finished and insisted I totake another 2 shuttles to terminal C so I can just talk to another service rep while dragging my family of 4/ kids in tow.

Everything was good. Please have a wheat free option for snacks in the future.

Not delay for a few passengers. That was uncalled for. If idiots can't make the flight on time thats their fault. Why should I be punished for them? No more holding the plane for one or two people

How can I review what was denied to me. Instead of offering to let me pay for the ticket I got booted of my flight with no way home and no choice but to purchase another ticket for 12 hours later. Filing a complaint with the DOT

I like them since I live in Alaska and I don't have much choice

I had a great trip. Everything was on time, easy boarding and kind attendants.

Good legroom, good food. Great landing, comfortable seat, good communication from pilot and crew. I wasn't thrilled that we were an hour late but it happens. The only two minor things was that the garbage pickup was slow and your windows need washing. Overall we will beback

In order to watch a movie you have to buy wifi access

Very close to on-time takeoff and landing. Attendants were all great - Julia was best! Joined the Alaska Air Rewards and will fly with them again!

The plane was a rather tired 737-800, with old style small luggage bins. Poor air flow. USB charger in the infotainment system was not functioning. The flight was 2 hours late due to crew rest requirements (not their fault). On arrival in Seattle, waited on the tarmac for 30 minutes with very few updates from the crew.

The ac must have died, it was way to hot on this flight. Boarding g was chaotic. The flight was delayed for boarding. Not a great experience.

The crew was very inconsiderate and rude. My flight was scheduled to depart at 6:00am. I received a call from the crew at 5:40am, asking if I was going to make the flight because I was the only one that hasn't boarded yet and boarding ends at 5:50am. I let them know that I will be at the gate in a few minutes, before the 5:50am cutoff. When I arrived at the gate at 5:45am the gate was closed. Departing early on last minute notice without having all passengers on board is inconsiderate and unprofessional.

Very easy to use and convenient, you can perform any action within the same portal

Okay considering we had weather delays which the Pilot notified us of immediately!

The boarding was organized and informative but the plane was tight meaning that you were sitting on one another and extremely uncomfortable. It’s disappointing that can’t have common seating comfort on the plane.

Everything could have benn better. Short fly, no food, no entertainment and no wifi.

Stop changing gates. Stop cancelling flights Stop moving my seat.

The staff was frielndly. The plane was terrible, it was too small and should be decommissioned. There were no back seat screens at all. The only beverages we had a choice from was coffee, tea or water. The only bathroom in the back was behind the flight attendant's jump seat and wasn't working. And I literally felt like I was sitting on top of the guy next to me. It was terribly hot in the plane and we had to sit on the tarmac in Chicago for 1/2 hour due to congestion in Mpls. Wouldn't they have know that before they even boarded us so that we could have sat in comfort in the terminal?

Among the poorest flights I’ve had with Delta in a while. Entertainment system failed completely on a 7.5 hr flight. Crew seemed distracted and not the normal friendly crew. Flight overbooked it seemed… very crowded.

Kayak booked this flight with only 1h 20min layover in Chicago. This made it impossible for me and several other passengers to reach this flight. Moreover, the gate closed boarding in spite of several passengers still on their way without waiting even one more minute. However, the plane departed with 20min (!) delay, i.e., there would have been at least 15 min time to let the delayed passengers board without causing any delays. I complained and as a "thank you" the attendent booked us on the last (!) flight to Indianapolis ~7h later! Thankfully, I caught the spitefulness and the United customer line rebooked the flight to an earlier flight. Although I can't grade this particular flight since I never had a chance to take it, Kayak made the mistake of a too short layover and the crew at the gate was awful.

Flight did not have wifi service. It was experiencing technical difficulties. Definitely and old plane that needs updating.

Old 757 with poor entertainment system. United no longer partners with United for free text and email. O'Hara an absolute disaster! Limited gates clauses two hour delay. Unfortunately this appears to be the norm.

It was a good experience, unfortunately my checked baggages were come late and not arrived on time.

Very stressful to locate United Airline boarding area, delayed flight, changing boarding area again to another location with all tiredness 😩. But flying was fine.

Unbelievably smooth boarding at IAH and the flight attendants were top notch.

Comfortable seating POS to IAH. Food options were satisfactory. Good seat from IAH to ANC. Food options could be better.

There could have been better food options in economy on the long 7hr trip from IAH to AM.

Great experience. Boarding was fast, staff were very nice and funny, everything at the seat worked well.

Flying to anchorage would have been cool but the weather got in the way

Good flight, regional jet so old and seats could use an upgrade

Couldn't make the flight because connecting flight was canceled.

gate crew was courteous and helpful, flight attendant was nice and friendly once we got going. But we pushed off from the gate relatively on time, then sat there like 10 ft away, for an hour, with no announcement or explanation. Taxiing then took forever, and I get that there was runway congestion, but would be helpful to keep us posted on whats going on

The power outlets were not working for my row. Also felt like the seats have gotten smaller. I was in the window seat and felt like suffocated, as the two passengers next to me were tall and wide.

Terrible. The flight I booked had a convenient departure time. Quick layover. And an arrival timed that worked for the people who had to pick me up. Thanks to delays and rebooking I got none of those things

I had my flight of Cedar Rapids. THen Chicago to Boston. Flight out of Cedar rapids was delayed by 12 hrs. Had to drive to Chicago to catch my flight

Long delays to board due to mechanical issues with plane.

Flight was delayed, boarded, sat at the gate for more than 30 minutes, left the gate then waited on the pad for another 30 to 60 minutes then returned to the gate, deboarded and was cancelled... alternative flight was not booked automatically. Waited in line for 30 minutes but fortunately an alternate flight to a different destination was found ... no thanks to the travel agent used by kayak

The flight from Milwaukee to Dallas was great the staff absolutely amazing. After that EVERYTHING WENT DOWN HILL!!! ABSOLUTELY HORRIBLE!!! WILL NOT FLY THIS AIRLINE AGAIN

I was very unhappy with the lack of communication from the cockpit. It took close to a half an hour before we took off after the doors were closed, and we got no announcements as to progress. It would be nice to get some acknowledgement of the situation and updates as to when we are taking off.
