I like flying first class, and United has a nice one

Unbelievably poor service from flight attendants. They didn’t even do water service on a four hour flight. Just disrespectful.

Seats had less pitch than a regional jet. Food was OK. Have to buy alcohol on US based carriers flying international. Boarding was a mess. Did not have bags but overhead space was gone quick. Would like to see the airlines enforce the one bag over and one bag under policy

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Crew was excellent. This was a relatively long flight though and had very little leg room, and no entertainment.

The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

Flight was delayed and missed my connection Lufthansa didn’t respond.

the delay for 3 hours was understandable due to weather conditions but the flight should’ve provided some on flight compensations or at least provide more food.

United could have one single once of customer service. No human United employee would help me with the invalid mileage plus number, they said I had to speak with the computer.

Update to handle the delay was very bad, crews no smiles or welcome or thanks. Don’t care attitude

No gates avail at DFW so our incoming had to wait 30 mins for a plane to push back because they Had mechanical. We boarded 90 mins delayed and then we had a mechanical. Come on American…do better. Also at my seat the tray table had not been cleaned. Floor had not been cleaned. But captain and flight Att were very picture and apologetic.

Flight was canceled. I asked to be rerouted to OKC and then took an Uber.

AA did not allow to board a flight because my connecting flight from DFW had been canceled. I got on another flight to another city. No service on the plane and I did not use their entertainment system.

Don't change gate multiple times make people run across the airport. Announce delays in a timely manner. Have maintenance crew ready. Don't delay and keep passengers on the plane for 3 hrs. on tarmac.

I booked an aisle seat and was given a middle. At 6'4" 230lbs, it is not ideal to fly in the middle row for myself and passengers.

Concern Regarding Significant Gate Delay and Jet Bridge Issue Dear Customer Relations Team, I am writing to express my disappointment with the experience I had on my recent flight AA 2414 on Sunday January 18, 2026. What should have been a routine departure turned into a frustrating and avoidable delay due to an issue with the jet bridge at the gate. As a result, the flight was delayed by approximately 90 minutes while multiple gate changes were attempted. The lack of clear communication during this period made the situation even more challenging. Passengers were left uncertain about the cause of the delay, the expected timeline, and the next steps. This not only disrupted travel plans but also created unnecessary stress for everyone on board. I understand that operational issues can arise, but a malfunctioning jet bridge and the resulting extended delay suggest an area where procedures or equipment maintenance may need attention. I hope you will review this incident to prevent similar disruptions in the future. I would appreciate acknowledgment of this concern and consideration of appropriate compensation for the inconvenience and lost time caused by this delay. Thank you for taking the time to review my experience. I look forward to hearing from you. Sincerely, Dion Dillard

They made me pay $40 to check a bag that was listed as free when I bought my ticket. Then before boarding they offered to check any bags free.

My seat tv didn’t work the whole trip. And the seat space is too small despite being seated at the front.

The seat cushions were very worn so they were extremely uncomfortable.

It was costly and difficult to check in. $85 to take a small suitcase with me, carry on or checked and $75 on the return trip, Plus $25 if I didn't check my self in check in $25, because I couldn't do it on the kiosk. Small very uncomfortable seats, waited on the runway for near an hour each way. It was my worst flight to date.

Due to weather, my flight was delayed, further delayed, then canceled. I eventually got through to a support person who helped me find a different route out of MSP, but to get to DIA, they didn't want to, but eventually did help with the connection ticket purchase. But even this replacement flight was delayed time and time again, and I would have missed my connecting flights and I didn't want to get stuck in a layover city, so after 12 hours at the airport with two young boys who were very tired, we just cancelled our plans and spent the week at home, instead of Nana's.

I knew going into this that Frontier, being a low cost carrier, would be pretty bare bones and charge for most extras but this was made up for by the fact that the airplane was a reasonably new Airbus, every employee was great and best of all, Everett Washington is an amazing airport - thanks Frontier for flying there!!!

Seats were new and comfortable. Staff was fine. Missed my connection due to weather -which wasn’t their fault- but got no help at all. Gate staff sent me to customer service, which was and stayed unstaffed. Sign with QR code directed me to call or chat. Chat was useless. Call was returned after an hour. No itinerary offered by Frontier could get me home in less than 30 hours. Rebooked with another airline and got a partial refund that came to about 10 percent of what I paid to get home.

The experience was good. No frills but I got there safe and sound and on time.

As every law enforcement agency I could imagine surrounded the plane and we didn’t disembark for 2 hours and then had to stick around for another hour to go get our personal belongings after leaving them behind and being bused away from the plane, it was scary and inconvenient. We were given no information as to why this was happening. Lack of communication with passengers was disappointing.

Frontier Airlines was AWFUL. I was an hour early for my flight and the lady refused to check me in. I had to purchase a whole new ticket with a different airline.

Late, terrible communication, horrible planning of passenger seating until the literal last minute. One of the worst flying experiences of my life. Y'all suck

First of all, we never got on the connecting flight to Denver. They delayed our flight for two hours. If we would have gotten on that flight, we would have been stuck in Denver for 13 hours. So we re- routed our flight for a straight through flight to Oklahoma two days later. THEN, they delayed that flight for two hours. After that we were able to finally get on our flight and come home. Frontier Airlines - one of the worst airlines I have ever been on.

Terrible communication with weather delay, lost baggage, near impossible to reach customer service
