Could not get my connecting flight boarding pass until four hrs before departure! Ver annoying especially since the staff could not explain why!

The flight was flying with 30% capacity. The flight my seat from preferred seating to back of the seat. Even though i can understand that this was to balance the flight weight. The flight attendance decided to do the serving near my seat and in the middle , their noices woke me up from sleep , when i realized that the service has ended and when they were going back asked for a coffee, for which they answered they have completed teh service in my location. That really upset me as they woke me up and also rejected the coffee i asked. I ended up landing with a headache, thanks to the crew that screwed up my travel

Delayed. Hot. Passenger next to me was so large I couldn’t move.

Same experience as the flight from Norfolk to Atlanta where people are boarded in zones that don't make sense. People behind you on the plane will get on before you and they take the luggage space on your row.

The boarding process doesn't make sense since some people that will sit behind your rows are boarded before you and then they take up the luggage space above your head. I then have to wait for people to get off the plane before I can go back to get my luggage.

Good flight. Connector flight was delayed so made a short turnaround in Atlanta which was stressful. Otherwise, great crew, Staff in ATL was very informative about the delay and ensured people their connections were fine. Notified the ones that were not. Great communication.

The flight went very well, but the flight attendants didn't serve and food or drinks other than 1st class due to rough air but to be honest it wasn't that bumpy and I felt that they could've at least offered water and coffee perhaps. Also serving 1st class only is a bad look. I've been in 1st class many times and I would've felt that if the turbulence was too rough for the main cabin, it would be too rough for 1st class too.

There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.

My seatback screen didn’t work so that sucked because that’s what I was going to do on the plane.

Left a few minutes early. Got in 15 minutes early. Very attentive service on board. Very organized boarding.

The flight was delayed so we were dead tired, and after that the turbulence was horrible. I was very scared.

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

Ineffective communication with United resulted in lost baggage. Their Baggage Tracing counter at MUC was shut down from 11:00-14:15 on my arrival. Undertrained, underinformed staff had me Running all over MUC to find someone to help me to no avail. Staff was rude, unhelpful, and unable to effectively use the systems they did have operational. They refused to contact United in any way or provide any accommodation or other resources while I waited for my luggage. This has destroyed my downstream itinerary. If they had even the slightest visibility I may have been able to reschedule/plan, but again, their staff provided nothing, and did nothing more than their website, which doesn’t even work on a standard phone browser. Miserable failure at all levels that weren’t associated with the operation of the aircraft.

Sat next to a one year old. She crawled all over the place and made me laugh.

The Crew and the food was the worst I ever had in Business Class. First they told us there were no space for carry on. It was plenty of space over our 2 row seats, we had to ask to let us travel with it which was accepted. They were aware that we had to run for the connection due to the previous flight delay. Have us one hour waiting for more customers and not even offer a glass of water. Then started the service and they started to serve other passengers drinks in business and did not offer any drinks until they serve our pre ordered meal and I ask for something to drink. I had to wait until they finished to serve all passengers until Inget something. The crew was the worts I ever had for Business Class in my life.

Not great experience - we were super late boarding due to issues with aircraft. Then when we finally all got onboard and seated and they started taxiing out to the runway they just stopped then turned around and went back to the airport. Apparently the crew “ran out of time” to legally fly us. They mentioned that they were about 2 minutes away from taking off. I understand the rules and safety but kinda wonder why they would have bothered boarding us in the first place? Had to go all the way back and de plane and then wait in a HUGE line to get a hotel (this is somewhere around 2:30am) finally got to hotel by Uber (no shuttle after 20min so gave up) and they ended up putting us all back on the same aircraft at 10am next morning so got about 2.5 hours sleep. They did give us. $250 credit, but it was a São Paulo Brazil flight out of Dulles. The flight and everything was fine.

Starlink wifi on the Embraer E175 is an excellent experience. I was able to connect and work from IAD all the way to approach into BTV.

7 hours delayed due to operational issues on United’s end. Basically laziness.

Flight delay for mechanical. Inbound arrived on time. No one said why mechanical delay.

It was an older plane. First Class was not especially roomy or comfortable. It was a short flight so there were no meal but they did offer mixed nuts which used to be normal but now is rare. Crew member was very polite and professional.

Flight boarded, departed and landed on time. Excellent service from flight attendant in FIRST

No Snacks or Entertainment. The flight was short, snacks should still be given.

This was one of the most frustrating travel experiences I've had to date. I had changed my flight day of to this one as it was slated to depart on time. It ended up being so delayed that my original flight took off before this one did. The boarding process began but eventually stopped and everyone had to get off the plane as a problem was identified. The person at the front desk just tried to laugh it off as if this wasn't already a huge inconvenience. From there, we eventually got to board only to sit at the gate for an additional hour because of some additional issue. This was extremely frustrating and caused a lot of stress.

It was a little concerning to hear the ground crew arguing with the flight crew over baggage space. Instead of taking them and checking them, they started checking for space in the first class cabin moving items around like the flight crew didn't know what they were doing. I was embarrassed for them.

The boarding process needs to be fixed. The zone don't work, especially when there is hardly anyone in zones 3, 4,and 5, leaving the majority of the passengers backed up in the aisle, especially because passengers seated near the front are blocking passengers who are seated in the rear of the plane. It would also help if the size of carry on bags was more strictly enforced.

delayed due to weather. Could not communicate with family since the wifi was broken

I got sick nothing contagious but distressing and the care I received by Kayla? Keighly the flight attendant will be memorable for ever. Thank You

We were told the flight was delayed 5 times, then it was moved to the next day.
