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

Always pretty good as far as I see it. Staff was friendly and process was quick to get on and off.

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

It was terribly delayed with zero support from united airlines. I reached at 1 am in the night. They did not provide any option to change the flights.

For the expense of first class, the seats could have been nicer and higher tier snacks would have been nice.

They delayed the flight 3 hours because it wasn't full they moved us to 5 different gates probably the worst airline ever not even spirit is this bad.

MY FAMILY'S LUGGAGE WAS LOST FROM ROME TO BARI. I WAS THE ONLY ONE THAT RECEIVED MY LUGGAGE FROM ROME TO BARI. AFTER DEPLANING IN BARI, WE WASTED A LOT OF TIME AT BAG CLAIMS LOST AND FOUND REPORTING THE CLAIM AND PLEADING FOR THE BAGS TO BE DELIVERED THE NEXT DAY. WE WERE TOLD THAT IT TAKES 3 DAYS MINIMUM TO DELIVER. MY DAUGHTER AND MY GIRLFRIEND NEEDED THEIR PERSONAL THINGS AND WE WERE STAYING 3 HOURS AWAY FROM THE BARI AIRPORT. WE HAD TO DRIVE 3 HOURS TO THE AIRPORT TO COLLECT OUR LOST LUGGAGE THE NEXT DAY. WE ARE NOT HAPPY WITH THE EXPERIENCE

Sucks ! All three flights I was on this trip were delayed.

It was ok until we got to DC and I wanted to use my United Club pass and the snobbish receptionist said that they don’t take one pass. It took me everything itch of patience not to tell her off

Flight was well orchestrated, made up time despite circling a bit all good on United. Travelers can just be so into themselves that common courtesy has gone out window for some, but that’s not on United.

Easy boarding. Rows are smaller but that may be an older and bigger me now :)

Poor communication ahead of time about flight delays and old planes/other equipment.

Flight was on time and there was an empty seat next to me. That makes for a good flight!

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

There's nothing I liked about it. For first off I scheduled this trip two weeks in advance then they delayed my flight which messed up my whole trip. So I scheduled it for the following weekend thinking there won't be a delay and guess what as soon as I got to the airport we said in the airplane on the tarmac for an hour and a half. Not only was it delayed I missed my connecting flight meaning I had to stay the night at Dallas-Fort Worth airport sleeping on the floor. I will tell you this I will never fly American airlines ever again I have had nothing but horrible experience with them and I just throw money at them

They changed my seat from one that I had paid for as an upgrade to a regular seat at the last minute.

Very aggressive and unhelpful ground crew. Wanted to check my hand luggage for 3 flights. I had lots of delicate items and computer equipment. So the silly lady wanted to rebook 3 international flights because of a carry on. What nonsense. The baggage handler suggested I put it under my seat - so I did. And this was during the rebooking chaos of the Microsoft crash. She was the most arrogant annoying and aggressive ground staff member I’ve met in 20yrs. (AA flight out of Houston).

Was as expected. Good leg room on planes - much appreciated.

I know that there is nothing than can be done about rude customers. I did find a couple of them were very rude and inconsiderate In my case the guy who was sitting in the same row as I was in, was trying to watch a movie with no headphones, a crew member did ask him to turn it down or off (thumbs up for that.) Another thing, as we were about to land another young man must have taken his phone off airplane mode was talking with his friends and using fowl language which I found inappropriate to the ppl who were sitting in the same row as him and other ppl around him. I understand how no one wanted to address this person and not get involved. We all just wanted to get home safely with out any incident.

The food service was limited and not good. For a seven hour flight they could do better.

We were delayed three times ,and that destroyed my plans, and reservations

The reps working at the airport counter were dumber than a second coat of paint.

Delayed each time on a round trip with no significant weather interference. Updates to flight times came after the fact. 30 min behind in boarding and board and phone still show an on time departure. Some mysterious extra 300 miles that came so surprising they had to fuel while we were already on board?

Airline changed the gate from Terminal A to Terminal D which is quite far and only sent a text message few minutes before boarding. Around 50 people missed their flight and as plane didn’t wait for them.

Bad experience… crew are extremely strict with personal bags… they overcharge me coz my bag was one inch H

Well I mean u get what u pay for so 🤷‍♂️

I purchased a carry on bag online…was supposed to cost $72 but after a whole slew of bs charges, the total was over $175.00. Because of these hidden charges, I will not even consider flying Frontier ever again. It’s just not worth the hassle. I’m scratching this company off my list forever.

Plane was clean but they do not allow bag drop until 1 hour before flight. Just encouraging late fees and other issues. The worst I have experienced. Total hostage situation, pay or you miss your flight.

Everything was good, and most importantly on time. They have been extremely tardy in some of my flights

Flight delayed an hour. The turbulence was insane. Packed in like sardines. A coke was $4.95 no snack or a drink crazy
