For an expensive flight to another country, United has a lot of nerve serving pretzels and no meals (unless, of course, you want to buy something to eat). Unacceptable.

For an expensive flight to another country, United has a lot of nerve serving pretzels and no meals (unless, of course, you want to buy something to eat). Unacceptable.

The food is terrible. The same pasta or chicken with bad taste and presentation

United have really come back. Airport and boarding process is clear and good, app and information also very good

The Sears in the 800s are not too good perfect Airbus why cant the new 737 fix that

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

It was probably one of the worst flights I’ve been on. The restrooms were never cleaned or stocked. The food was very subpar, and i usually enjoy airline food, so I was disappointed. It was just all around a bad experience. The only saving grace was the flight attendants.

After a delay at the gate, C3, at Ohare on Sunday, I left my Blk ski coat on the bench at the gate, lost! Please review my lob claim, thx.

Very bad! They kept delaying my flight and wouldn’t do anything about it

They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.

The only downside was my cell phone charger wouldn’t work in the charging port but everyone else’s would work in them all. My cell phone cable works fine in my hotel room in Frankfurt.
