Nothing unusual. It was fine. I hate having to pay extra for my seat.

Nothing unusual. It was fine. I hate having to pay extra for my seat.

The flight was so late that I had to change connecting flights, turning a five-hour trip into a fourteen-hour nightmare.

Late departure due to large number of wheel chair patrons. Used to having a box of snacks to select from in comfort plus. The flight attendant just rattled off what was available and asked us to pick. Felt rushed and uncomfortable. Seat was great. Prefer having the screen on the seat in front of me instead of having to pull it up from the seat side. Lots of room for my carryon under the seat in front of me.

My flight consistently said it was on time and the plane didn’t arrive until after 30 minutes after take off and nothing was announced to passengers

The fight was about 2 1/2 hours delayed, but that was weather related. The flight was also overbooked. But we were in Comfort plus so the flight was fine for us.

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Flight was late. Club was full. Experience is exactly what I expected.

Inflight entertainment stopped working as we taxi to runway and never worked again until landing and taxi to gate. Grrrr

The seat could use more support or cushion. I'm in my 50's and have back issues so the seats are a bit hard for longer flights.

Flight home lot's of room shame I never noticed that they ripped my suitcase and didn't notice it to I got toy destination and had to buy new set

I was pleased and I had a very good experience. The staff was friendly and attentive.

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 flight from Cleveland to Newark was great. The connecting flight wasn’t so good.

This was a short flight with no food. The attendants were great but the comfort was poor: just to cramped. The flight from Denver to Frankfort was excellent! Seating was roomier, food was good, service was good. This was a great experience.

Delayed over an hour due to paperwork not being filed correctly. Forced to change planes.

I still prefer Delta, but Delta doesn’t fly to State College PA.

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.

The flight attendant was very kind and offered my son a snack for free.

Flight was quite late as there was no pilot Crew is usually excellent, this flight not as good as usual there were more mistakes, slower and less friendly service But honestly the aircraft was too cramped and uncomfortable for a 4 hour flying get so, do to the aircraft liability the very best you could ever do is mediocre.
