The flight was delayed by two de-icings. The seatbelt did not work correctly. It did not stay tight.

The best airline I have ever travel , really good customer service, attention and service !!

The seats on the aircraft are like sitting in a rock. During the boarding process they recognize Active Duty Military, why don’t they recognize Retired Military. I’ve always preferred Delta, this flight confirmed why I still prefer Delta.

It was literally one of the worst travel experiences ever. My flight got delayed by over an hour and there was no communication of this from the gate staff. I realized it by checking the screen periodically. Once on board the flight attendants continued to serve alcohol to a man who was clearly already drunk and that was making a bunch of commotion. Never again will I fly United!

At least the delays were short. Business class, even in the new planes is very crowded now with crappy tray tables

I flew Delta last week and United Airlines is a poor substitute mechanical problems with the plane and shitty food among other things made my travel experience what’s become to be expected from United no way is it ever worth the money they make us pay

All good except paid for wifi that did not work

No in flight entertainment, gate employees were very quick and impatient, plane was uncomfortable

Flight cancelled due to fog. No other flights available for 36 hours. Directed by United to book passage on another carrier, and submit receipts for reimbursement. Did that. United now states they will not reimburse. Currently out 2 grand.

One the best cabin crew team we have ever had (I have flown globally for more than 2 million miles), food was good and wines choices were great.⁰

Our particular exceptional experience was with Johnny at JFK at check in. He was the kindest, most accommodating agent I’ve ever encountered taking extra steps to help my husband and I with our extra baggage. I hope that he knows how much he positively affected our trip.

Because I bought my ticket from Underpricer, I could not check in online. I could only check in at the airport and that was deeply frustrating because I had to arrive very early. The flight also departed 45 min late and passengers were given no explanations about why we were delayed. I was worried I would miss my connecting flight. Once on board, however, the flight was fine.

Crew was helpful and cheerful especially when they had no refreshments to work with. The plane was never serviced and had nothing but limited water and coffee onboard. For the price point, a concern of services.

I bought wifi and most of the flight could not even use it my apps would just spin. I couldn't even listen to music. super frustrating.

Seating was horrible. Small seats. Access to flight information and extras very iser unfriendly. Kept losing internet after paying for it. Staff in madison was as unprofessional and unhelpful.

There were several different delays but we ended up being delayed a total of 40 mins or so. It was annoying we had a gate change which made it take longer to leave DFW, and we had to check our carry on. Ugh

The counter/baggage counter was busy and so many people missed flights. We got stuck sitting on the plane over 2 hours at the gate while they were doing an inspection is wrong. Many of us missed our connecting flights because of it.

Our flight was changed from Madison to DC to Madison to Charlotte.

We were told we had no flights before our flight was continually delayed then cancelled.

Boarding was relatively fast and easy and the crew was attentive throughout.
