I paid extra to choose a seat. When arriving at the gate after a very stressful check in at the airport, realized did not get the chosen seat that I PAID for. When I called the airline I was told I did not pay to choose a seat and could not be refunded, but I DID pay extra to choose a seat. And of course, got stuck in a MIDDLE seat. Since the seats are now crammed together, this is especially uncomfortable. The check in for baggage was ridiculous, it was a mile long and the kiosk to check in for the flight was very confusing. We finally sought out help and a very rude representative quickly went through the kiosk and printed a boarding pass that did not provide the PAID for chosen seat. Didn't get to get on the return flight because the flight coming in was delayed several hours, missed the flight by 3 minutes!!!!!!! You really can't hold the door for 3 minutes for a passenger you KNOW you are waiting for??? What stress and had to wait 4 MORE HOURS to get a flight home because you could not keep the door open 3 minutes. 3 minutes. Had only 20 minutes to get from flight to connecting flight and was accused of taking too long to get from gate to gate in Chicago. Flights were delayed all day long coming in and going out, you would think you could wait 3 minutes to allow passengers to get to the connecting flights. HUGE inconvenience, stressful and makes for a really LONG day when the flight leaving Des Moines to Chicago was horribly delayed, already had a horrible experience and missed the connecting flight by 3 minutes. 3 minutes. Airplane was still there, the door closed, why on earth is it such a huge deal to wait a few minutes when flights were already delayed ALL DAY LONG and why is it such a huge deal to REOPEN the door to let another passenger on??!! I used to like Alaska Airlines. I just plain hate flying in general now. The airlines have 0 (zero)care about the people buying tickets and making travel plans and how stressful flying is now. Zero care.

They overbooked the flight! Or they said it was over weight, very unnerving as flying is a gamble anyway. They were waiting for six passengers to give up their seats, before they would board the flight, they were offering $1100. I’m guessing towards the purchase of the next ticket which I would never purposely fly with American Airlines. It was just the only flight available with what I needed. American Airlines is the top two worst airlines to fly with. And then after waiting an hour and four minute delay departing they ended up seating the people that they had asked to give up their seats anyway turns out they were not overweight after all. So all of that in a delayed flight and a delayed landing in Des Moines for nothing American Airlines is in competition with United Airlines for the worst airline to fly with.

The seat was comfortable, but I paid for upgraded seats and they did not state that there was no outlets for devices.

Extremely professional crew there are very friendly and first class. Everything worked well on the plane. Food was to be expected. Drinks were very good. Shout out to Charlie in first class who was an excellent flight attendant.

Thanks for all you do to keep us safe and on time!

I like flying Alaska Airlines. I think the staff are happy, the plane is comfortable, the entertainment reasonable, the food acceptable.

No WiFi. Terrible food. Very long walk to the gate and from the gate after landing. Gate changed without notice.

I really hate the seat assignment at the gate. I understand it is so families can sit together but it caused me and others a lot of unnecessary stress and confusion, enough for me to not fly Alaska again. The app is so awful that it did not even update my seat assignment on the boarding pass but sent me a notification of my seat... it showed in Apple Wallet but not in the Alaska app itself. That only made the stress worse. I think most people like myself prefer to know where they are seated at check in 24 hours before so they don't have to anxiously hang out at the gate the entire time. This is not a good use of your agents time either to be dealing with all of us asking where we are sitting. You should automatically assign the multiple seat purchases to be together before they check in and fill us solo travelers in those gaps as we check in.

Great. Went right to the desk and the people were helpful and kind. I was able to get my boarding pass in under 5minutes. They made sure I received the text.

The flight was delayed so we didn’t get into San Diego until almost 1 AM. Otherwise, it was lovely.

I'm 6' 2" and even in economy plenty of leg room

Horrible experience. Delta delayed the flight to 11pm which happens. Apparently the pilots were there but we were waiting for flight attendants to arrive from Detroit and they were delayed. They could have made arrangements but that’s fine. What was truly horrible was that at 10:50pm the pilot comes out and says the flight will be cancelled but hasn’t been cancelled yet in the system. It’s being cancelled because the pilots have timed out. As soon as that plane got delayed past 10:50pm delta knew it couldn’t fly. Yet they made us wait around for hours. When the flight finally got cancelled all the area hotels were booked and flights for the next day were unavailable until midday. All I wanted was to spend one day with my family before needing to fly abroad on another delta flight. That will be my last flight with them. I’ll take my 800k miles flown and annual spend to an airline that isn’t so thoughtless.

THI IS THE 3RD CONSECUTIVE FLIGHT FROM ORD TO MSP THAT HAS BEEN DELAYED 2+ HOURS. CRAZY

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.

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!

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?

This was one of the worst flights I’ve been on in years. I upgraded to comfort and had such an uncomfortable experience. The person next to me was oversized - which I understand - however, they took up their space and mine. I could only use about 50% of my seat space to not be physically touching this person the entire flight and there was no spatial awareness. I also could not use the seat outlet because their body was obstructing it. It was very inconvenient. Their body kept touching me repeatedly during the flight and I felt very uncomfortable. To pay more for an upgraded space and then not even being able to use it was highly disappointing.

Price was crazy watch it if you Chan he your flight

On time, easy boarding. Anytime you sit in an economy seat, it’s uncomfortable. New plane and the bathrooms were in the galley at the back of the plane which seemed odd.

Terrible service - they don’t want to be there and bad food. Entertainment system in economy from the 2000s

No drink service but there was no N/A as an option to choose. Seats were extremely tight. I am under 5.5 and I bumped my knees have no idea how taller people could manage.

Flight delayed, last seat on the plane, no arrival Gate available due to the plane departing late

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.

First class snacks - stewardess gave out multiples to everyone until there was almost no selection left when she got back to me last in first class cabin. Nothing left that I would eat.

My feedback from the trip to Columbia to Chicago was meant for Chicago to Denver.

The WiFi was out gr entire flight. Had to Diane for almost 1 hour to wait for a gate to open up for plane to dock. Very bad experience.

DELAYED AGAIN and AGAIN and AGAIN - not only that, you delay in 20 minute increments for hours and hours instead of having an accurate delay understanding.

AA was fine....the overall experience was subpar, but not due to the airline due to broader issues

No ground air conditioner for the plane. Very hot and humid prior to take off which was an uncomfortable period of time.

Check-in process was poor, very poor, only one person to check-in all passengers, so if one passenger had a check-in issue, all other passengers were delayed. All check-ins should have two airline staff to check-in passengers.

The flight up was great no issues. The flight back home was a cluster. I was told the plane I was waiting on was giving to another flight which caused me to miss my connection flight. Granted the airline did great with getting hotel and vouchr for food.

Flight was delayed and so much of inconvenience related to the gate change.

Nothing was good about this flight. Although the flight actually departed more than 3 hours late, due to “air traffic control management” we pushed back from gate 2 hours and 20 minutes late and proceeded to sit 100 yards from gate for and then n tarmac for another 1/2 hour additional 20 minutes

During the flight I suddenly felt very sick, and no one from the crew even tried to help me or check on my condition. They seemed completely indifferent and showed no concern for my well-being. I was very disappointed by the lack of care and compassion. I hope the airline improves its customer service and trains its crew to respond better when passengers need assistance.

Flight was canceled. Most upsetting was message from Kayak, stating that the flight was canceled and click with Kayak for details regarding rebook, refund details. THERE'S NO INFORMATION PROVIDED BY KAYAK EXCEPT THAT FLIGHT IS CANCELED. AND NOW THIS SURVEY TO FIND OUT HOW WAS THE FLIGHT !!!!!!!

Better than expected. Staff were friendly and nice on both flights.

Just know that everything, and I mean everything is “ala cart”. 60$ just to put something in the overhead bin. I will never fly Frontier again nor do I recommend them to anyone else.

Great for the price. No wifi or entertainment, but gate agents and crew were fantastic and we boarded quickly and left on time.

Our flight was canceled for no known reason. We weren’t told until we were checking in at 5:00 am. This was after our last flight with Frontier where we sat on the plane for three hours (not an exaggeration) before we took off because of a mechanical issue. We won’t be flying Frontier again.

I didn’t have enough time to catch my connecting flight and had to use a different Airline. I will be requesting a refund.

I brought a ticket and car rental through Travelocity. There was no where to add a KTN. So I thought i’d add it by looking up ticket on frontier website. I tried 3 times with the frontier chat bot to add my KTN it never updated my boarding pass. So then I tried showing up early to do it in person at the airport. The first employee update my ktn in the system and gave me a new boarding pass. I was sent back by tsa to join regular line. Then I was told to add my Ktn. It would cost me $25 extra. Given the length of the cue I did pay. Congratulations! BUT I will NEVER fly frontier again. Plus the plane was very old. It had actual ashtrays and old looking tray backs. Worst travel experience ever. Im warning my friends and family not to use frontier ever.

It was delayed 9 hours for operational reasons, despite the plane arriving to the airport on time.

Was just ok with over selling I guess. A lot of people in a short space and when we finally arrive i20 minutes, waiting to get out from the plain because we were waiting authorization for out boarding? Something like that.
