Three hour flight so snacks and basic drinks unless you pre buy as usual. Didn’t do my emtertainment as was tired after 23 hours of travel. You have to use your own device on US flights if travelers aren’t aware so if you only use your cell phone that can be small. Crew are great.

Awful. We got the last seats and they don't recline. We've been on this horrible journey since 6am and won't get to our destination almost a full day later. Oh and no food, either. Never again.

An uneventful flight is a good experience although one of the pilots gauges wasn’t working right so we had a half hour delay—no one can foresee that.

Plane was delayed and got me in past bedtime. But more importantly, my tsa precheck number wasn’t on my ticket so had to deal with the general line. Oh well, guess the delay helped that situation.

It was as good as flying can be, which is still very uncomfortable. Clean new aircraft, great crew.

Everything was good. The flight attendants were great. I was disappointed that there wasn’t any screens on the back of the seats to watch movies, tv, etc. I only had my phone to watch movies on.

Flight delayed due to engine issue. For 3+ hours still not on flight

Could have had more of a beverage selection than water and apple juice.

They only had one flight to my destination for the entire day. Six hour layover. Coming from their sister airline we didn't have any boarding grouping on our boarding tickets. Had to ask where we were within the grouping.

Flight was over an hour late, and we got notified every 15 minutes, beginning right at boarding, that it would only be 15 more minutes until we finally left about 75 minutes late. Of course, no compensation was offered.

Multiple delays and not straight answer from the United team

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

Food and flight attendents with positive dispositions and friendly behavior, more professional attitudes

Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)

Liked the hospitality . The ight took us 6 hrs to get from fort myers to ewr.

Wish movie and music choices changed more often. Mostly same from a month or two ago when I last flew.

Overall great. I was forced to check my carry-on backpack from EWR to BOS but it came out on the luggage carousel so fast I didn't even get delayed for my pickup.

Boarding was easy. RDU gates can get crowded, be prepared to be patient. Flight was smooth, with excellent service. Pilots really provided a lot of visibility into flight details. Plane and seats were clean and serviceable. TY!

It was good. Just that the seats could not be reclined. The people behind were not ready to let the chairs be reclined

My flight was delayed. They boarded us, then no sooner were we on the plane, they made us get off again and wait another 45 minutes before doing it all over again.
