It was fine for the most part. But the volume on the announcements was way too loud, and the cabin temperature was chilly. We had the hardest landing I've ever experienced- I think it hurt my back, and the tires squealed when we touched down.

Great, except the canon was so cold. Even the flight attendants put jackets on

Did not like the check in guy quibbling over a couple pounds at the luggage weigh in

Just having a little bit more legroom would've been nice.

This is related to my second leg of the flight, from Washington DC to SFO. I understand things happen, but I got home at 3 am for a 12:59 am landing. I live 10 min from the airport. Bridge breaks when a few rows of the plane are off? Maintenance didn’t catch that?

Boarding, time to take off, in flight offerings, and staff were all great. I recommend using UA for this short flight.

The food for long haul was poor compared to Singapore airlines economy. Pasta plain with tomato sauce . Singapore airlines give me Hagen dash small ice cream cup it was great. The choices of dinner course Singapore air also much better The crew mostly friendly. The economy seat are as expected.

Was 4 1/2 hours delayed. No food options, poor entertainment and cramped seats made worse by people in front reclining while we could not as in back row.

Ok, but comfort was lacking as the seats were way to small

The stewardess was excellent. Very accommodating in a quiet way, which was appreciated. The only thing that could have been better was the choice of snacks. Chips, cookies, etc. weren't an ideal way to start my day on a 7:00 a.m. flight. Offering fresh fruit, yogurt, or other breakfast foods would be great. 😁
