Had a crying baby and a toddler behind me so it was difficult to get comfortable. Searing was tight even for a relatively small person like myself (5’8” 155). Fast flight but arrived so early the gate assigned was still occupied by another plane so we had to wait for about 20-25 minutes to get reassigned to a new gate and get over there.

Had a crying baby and a toddler behind me so it was difficult to get comfortable. Searing was tight even for a relatively small person like myself (5’8” 155). Fast flight but arrived so early the gate assigned was still occupied by another plane so we had to wait for about 20-25 minutes to get reassigned to a new gate and get over there.

The check-in process is not the best They should have agents in site to help with any problem especially a rebook. Why does one have to get on the phone when there were at least 8 agents around that could have help?! Flying is stressful as it is and having someone willing to do their customer service will ease some of the stress.

I liked that the flight to Kosice was on time, the service was excellent and we arrived to Vienna early. The only thing I did not like, is that I had to pay for my suitcase $75. Bummer

The plane’s radio wasn’t working. This delayed the plane for an hour and a half. Then we all broaded and taxied down the runway only to get called back because the radio was still not working. Had to get off the plane and then find another plane making the trip 4 hours delayed. Maybe a different plane should have been chosen sooner?!?!?!

Late out of the gate, late to takeoff. No screens on plane. Uncomfortable window seat.

More water distribution throughout flight. Food quality poor and hot items delivered not hot on both attempts. Not United Standards

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

Haven’t used United in a while. Was surprised with the free blanket and earphones. Service was great. Huge plane. 9/.row.

The flight was very good. Only complaint was that the usb charging connection did not work for either me or the seat next to me so we both had to use our own portable battery to charge our phones. I also liked the fact that I could purchase Wi-Fi for an hour instead of for the entire flight.

Your seats in the last 5 rows are terrible. My knees were jammed into the seat in front of me and the lady sitting there decided to recline it. Jammed my knees bad. I don’t know if I’ll fly United again.

The departing flight from Newark to Charlotte was fine. It was the returning flight from Charlotte to Newark that was awful. We had scheduled an 8:35pm return flight time. We got delayed TEN times all the way to 5am in the morning! We were told over 4 different excuses as to why the flight kept getting delayed. First it was the flight crew needed to rest, then it was something technical with the plane, then it was something with air traffic control, and finally it was because they couldn’t find a captain and had to wait until the morning so the captain could get some rest. It was terrible sleeping overnight in the airport. They offered a $12 meal voucher. That was it! And the only place open in the middle of the night was Dunkin’ Donuts who didn’t even accept the voucher. They should have cancelled the flight much earlier on in the evening instead of just stringing us along hour by hour with more delays. Not professional and unacceptable. There was no refund for inconvenience. I probably will not be flying American Airlines again.

Checked in the minute I was allowed and still wound up in group 8 for boarding.

There were several issues with this flight. I have flown quite often internationally and I was surprised by the lack of presence of attendants other than meal and drink times. The food was not best but I feel that is the norm. We also had to get off the plane once in London via stairs and bus to the terminal. Anyone who had another flight had to then get another bus to another terminal. This causes me to miss my flight and have to rebook.

The boarding process was incredibly slow, as was deplaning. They started beverage service and there was an extremely small amount of turbulence, so they discontinued it. They said they’d resume if possible, but even thought the rest of the flight was perfectly smooth, they didn’t bother. Getting our checked bags took longer than I’ve ever waited and they couldn’t even tell us which carousel they were coming out on, so everyone was running back and forth for 30 minutes.

It was really good. The boarding was good and smooth. They even checked our carry ons if you wanted to without any charge.

The flight was delayed which was disappointing. There was no pre takeoff refreshment in first, as we had to wait around an hour in our seats before take off that was disappointing too. The inflight entertainment/wifi did not work, and the crew were slow to offer drinks in flight

Flight was delayed , waited in the tarmac for 3 hours and then came back and was cancelled

Extreme weather delays. Missed my flight to France and I ended up leaving the plane.

I arrived to LaGuardia Airport 50 minutes prior to my 6am flight but was told that I was too late and would have to flight standby to Dallas in order reach my final destination of Jackson, MS. Hundreds of people were in my situation but the agents chalked this up to being normal for any day. Had my been able to board my original flight I would have arrived at my destination by 10:30am. I didn’t arrive until 7:30pm which included a 30 minute wait on the tarmac. Strangely my luggage arrived at my final destination at 12:30pm of the same travel day. This was by far the worst travel experience I’ve ever had.

The food was horrible compared to other airlines, there was no space for the overhead bins for carry-on luggage, and the seats were very uncomfortable.
