The flying experience was great. The flight was on time with no boarding issues during a peak travel period. The short cut baggage drop and process was not smooth and efficient at Dulles.

The flying experience was great. The flight was on time with no boarding issues during a peak travel period. The short cut baggage drop and process was not smooth and efficient at Dulles.

Delays from united along with Newark air space caused delays. But an average flight! Unfortunately we come to expect delays from the airlines.

Fast checkin with the self serve terminal, good communication at the boarding gate.

Very friendly staff. The flight was on time. Need a bit heavy covers/blankets. It can get colder with a thin blanket.

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?!?!?!

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

This was a 5 hour flight with no entertainment and with a snack being provided (pretzels and fruit bar), which are both high in carbs and sugar. Nuts would have been a better choice.

Never nice, United Express partners always do an amazing job.

Everything was perfect except the pad at the top of the seat back. It pushes my head forward in a very uncomfortable position and it is not removable.

Good plane, crew, and flight. Boarding was a bit chaotic. Bathrooms were unacceptable. United DESPERATELY needs a new terminal at IAD.

No overhead space so all carryons were checked. No internet.

Flight overall was good. Landing was a little rough, but could be attributed to the rainy weather.

Check bag location is full of rude employees who are unwilling to assist with issues after talking to AA on the phone and relaying messages. The boarding was good. While on the flight it got really hot. Asked flight attendant if there’s a way to drop the temp and make it more comfortable as we are flying from DC to Miami so flying from cold to hot weather. No changes made. Stayed hot and uncomfortable on the plane. When asked again about the AC being down the flight attendant said no the WiFi was down but not the AC. I mentioned it was still hot. No changes.

Plenty of overhead space but forced to check my carry-ons both legs

The flight from CLE to JFK was fantasti! Pilots and cre were informative and accommodating.

No food, no entertainment. But the flight was really short so maybe they had to skip drinks. I was able to board early ONLY because I am old and decrepit and they let me pre-board. I RESENT your dumping us into category 9 if we do not pay up. And when I paid for a seat I was STILL given 9. The pre-boarding helps. THIS flight was exceptionally smooth, please congratulate the pilots.

Deparature was late, which is annoying but the arrival was fine and the baggage came early.

On time (actually a little early). Was a good and short flight!

No explanation of why there was no snack and drink service (unless requested) when there was service in the other direction.

The First class experience was really good!! Customer service was excellent.
