Flight was delayed. Had to get rebooked. Diamond medallion but stuck in a crappy seat. Rebooked flight then got delayed again. Then when we finally boarded, we waited another hour for a new crew. Then landed in JFK and sat for another 40 minutes waiting for a crew to come to the gate to be able to deplane. Hot mess all around, which unfortunately is becoming the norm for Delta

Flight was delayed. Had to get rebooked. Diamond medallion but stuck in a crappy seat. Rebooked flight then got delayed again. Then when we finally boarded, we waited another hour for a new crew. Then landed in JFK and sat for another 40 minutes waiting for a crew to come to the gate to be able to deplane. Hot mess all around, which unfortunately is becoming the norm for Delta

Terrible flight Delayed for over an hour without a reason Told all over head storage was full. It was not. Made to check our bags. What a terrible experience. Fly American.

Older plane and it came with Fleas and flea bites!

My seat was moved closer to the front of the cabin since I had requested wheelchair assistance to the gate.

Rough day of travel all the way around. Wrong info given to us multiple times and mistakes in their booking making our trip 10 hours longer than planned. I’m bummed because I fly Delta all the time and love them. Mistakes happen. Just bummed that this was a rare trip our whole family was traveling together.

My seat was changed at the last minute and I was moved to the last row, right next to the bathroom despite selecting my seat well in advance. I was also made to check my carry on due to space but when I got on the plane there was significant empty overhead space. Picking up my carry on from the luggage carousel added time to my trip which had already been extended due to delay.

All good on Delta's part. Passengers could be a little more courteous to each other.

Screen didn’t play movies, do I was pretty boated the entire flight.

Inconsiderate staff, plane was very hot, poor decision-making from the crew.

Flight was delayed due to needing a replacement flight crew. Delta changed the aircraft type in Detroit. One hour delay. But once in the air, good flight

Miserable. Active military on orders turned away from Lounge because not in uniform. This is completely contrary to United’s online lounge access policy. Sad that employees aren’t trained better. This is not the United Airlines my parents used to regularly fly with.

Too many canceled flights and kept my wife and I separated on alternate flights. We did not fly out of Denver. We paid a lot of money for the seats we wanted and now that money is gone and we did not sit together. That being said, the many agents were very friendly and did everything possible to help us.

3.5 hour delay known 12-16 hours before departure $15 meal vouchers which did not even cover cost of sandwich. Unable to reach agent for 1.5 hours, only then to be informed any rerouting to my destination would cost an additional $1000. Finally got rebooked on a 7.5 layover in Denver only to find out my original connecting flight was also delayed so I stood by and got on my original connection arriving only 3 hours late instead of 5 hours late. Overall journey was unnecessarily stressful and lenngthy!

When I got our tickets, my husband and I were easily able to get seats together (including a window seat). When we checked in at the airport all the seats were reset and we had to pick new ones, so we couldn’t sit together because there were only middle seats! Ugh that’s the worst. We were back so far we had to check our carry ons which was annoying because I bring an expensive camera that I don’t/cant check so I had to reorganize my items. Once we were seated on the plane we had to wait an hour to take off and they said there was some weather/air traffic in Denver but it was unclear. The lady I sat next to complained that our seats didn’t go back and we both got free complimentary snack boxes which were quite good. I wasn’t going to say anything about the seats, they were the typical uncomfortable kind. It would have been fine if the 2 hr flight hadn’t turned into 3 hrs. Not the best flight but also not the worst.

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

Not worth the price of premium class ticket paid, felt more like steerage.

The Wi-Fi was unavailable on this flight for some reason.

This was a Lufthansa flight, not United. The CSA at the counter, Ashley, was not only incompetent, but quite rude. Me and two other PAX waited over 7 minutes standing in front of her and another CSA and they ignored us. We joked that we must have accidently taken invisibility pills. She could have at least said "I'll be with you in a moment, I'm currently....". I could go on about how rude she and the other CSAs were (whispering, not communicating with me, blaming the situation on others, etc.). She would not work for me. Then, she gave me literally the worst seat on the plane. the worst. My seat kept getting bumped (rammed twice by the crew with their carts and about every 5 minutes by someone using the bathroom), listening to the bathroom all night, crowded seat, etc.

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was very clean. The crew was excellent. The flight was delayed slightly but other than that no issues.

It was delay after delay. Kept changing gates too. Not a good experience.

Departure down was really rough and ended up getting motion sickness on the flight

When you pay for Premium Economy on an 787 and you’re promised amenities for the extra money, you expect them to work. They didn’t. USB connector wouldn’t charge continuously. 120v outlet wouldn’t hold anything you plugged into it. The adapter would just fall out. The noise canceling headphones stopped noise cancelling in the first 15 minutes for EVERYONE. No one on the plane knew how to fix it so I couldn’t listen to any movies. I just put in my AirPods and went to sleep. Very unhappy with the crappy Panasonic entertainment system. I won’t buy premium again.

WiFi was down so no entertainment and I could not work either. The flight was Very turbulent at the end (the last 20 min felt like an eternity) I appreciated the pilot for getting us there safely. The flight attending in first class was kind and attentive to everyone.

Multiple gate changes and significant delay leaving DFW. Made for a late arrival

Our flight was delayed by 18 hours. Poor accommodations made and no apology.

This flight was canceled and delayed several times without explanation. The plane was freezing cold and no wifi for messaging. Getting off the plane was terribly unorganized and felt like it took forever….

Nothing, terrible travel experience due to weather and maintenance delays and was left stranded in Austin.

Experience was bad. 3.5 hour delay for a 2.5 hour trip. There was no r Transparency about the reason for the delay and it was done 30 mins at a time.

My flight was cancelled an hour before take off time.

Terrible airline. Cancelled the flight less than 24 hours before the flight. Caused me extra expenses!!! This will be the last time me and my family will travel with them

Very long delay of 6hrs with poor communication from airline. Another 5 pm flight to Miami left on time even though ours was scheduled to leave before that at 3. Would only fly Spirit when you have flexibility for cancellations or delays

Horrible They let some flights go while others where grounded or cancelled. Understanding the storm but there is always a way to get it done when you actually care about the people that are not from the place they are leaving from.

Terrible airline, NO REFUNDS!! Only credit for another spirit flight

Ridiculous that the plane was so late (3+ hours) and blaming weather even though other flights were coming and going. Also gate agent pulled me aside to measure my personal item. My personal item disassembled and fit in the slot. I was told that was unacceptable and I had to throw away the wheels of my pet carrier even though they fit in the slot. Per the gate agent, it had to be 1 piece. That's the spirit of Spirit- screw the customer to try and milk more money out of them.

Every last departure to get to our two destinations was horrible delayed putting us way after midnight to get to home and had to pay extra day for parking due to them getting us back to Myrtle Beach airport after midnight. The attendant on our flight from Newark decided to spray disinfected down the aisles and cause our eyes mouth and throat to burn and thanks to that we have suffered sinusitis. Shame on Kayak for having this airline on your site.

It was on time, no issues, everyone was courteous and of course, affordable.

Flight got diwngraded last minute and left us stranded. I was told I’ll be given credit for my luggage and seat upgrades but haven’t got anything yet

The flight was on time and nice as always for me with spirit but the cabin crew were not good. They left the lights on on a red eye for the entire flight.

The flight attendence were extremely rude and I am disabled

Never offer anything to drink ☹️ Flight delayed gate moved poor communication

Frontier charges 25 for the service of checking in and another 79 for a carry on. Will not take this janky air carrier again.

One gate agent in Sioux Falls ruined it for a few people on the flight. It was the usual, that personal item is too large, you are going to have to pay $100 to get it on the flight. One family with a baby were told that they had to have a passport for the baby to get on the flight. Also a Sheriff's Deputy needed to go on the airplane to return a lost cell phone to a minor on the flight. The gate agent would NOT let him go on without a boarding pass. I don't know who this moron was, but the sooner Frontier moves him where he can't interact with people, the better off they will be. Let's just say the deputy did the job that he needed to do and returned the phone to the minor on the plane, even with argument from a gate agent that thought he had way more power than he actually does. Very IRRITATING individual.

They never updated the boarding pass on their apps to show their delay

I did not enjoy the trip home on Frontier for several reasons: there is too much cost besides the flight, which was more than I would normally pay, then having to pay for luggage, and carry-on, seat (if you want to reserve when booking) then you must pay over $3 for a can of soda, and $4 for a snack. A cup of water is free.

9 hours of delay!! Was not able to check my luggage that I paid for!!!

Frontier won’t help you at the airport without paying $25. Carry on was $75. Then you get on the plain and every beverage or snack is also a charge. Seats are hard and real packed in. I would never fly them again.

The Frontier app wasn’t working. So I could not pay for a carry on the week prior to flying. They charged me 99$ at the gate to carry on a duffle bag.

Plane could have been more on time. More leg room .
