New Max 10, first class seats have been shrunk. End of a 20 hour journey, it was United not Lufthansa, just glad to get home

Seats are uncomfortable and left me in pain in my tailbone area. I got about one hour of sleep.

Delay of two hours due to some mechanical issue. Staff was wonderful and the pilot did let us know what was going on.

One of my checked luggage was damaged. Cracked on the top by the handle.

Not so good. Crew was not as attentive as they should have been especially if flying business class. Only offered dinner 2 hours after takeoff. My flight attendant seemed overwhelmed. Pushed my help button but no one came. I explained everything on my previous review.

I have been flying united for a long time but now I’m done

Delayed - leaving, delayed getting to the gate at destination. What should have been a very easy flight and experience was not.

Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

Boarding took a long time for a couple of flights. We arrived at our final destination an hour late. Others missed their connecting flight. We had no time to eat between flights. My checked in bag was delayed because it was in another flight. At least they gave us a voucher because of that. The staff was very kind.

It was decent, there was no WiFi on the flight but the FA’s gave everyone a warning once we boarded the plane. Unfortunately it didn't give me enough time to download my entertainment content.

American Airlines was horrible! The layover flight to DFW was delayed with no clear communication and for us having to stay the whole day which led to staying a night in Dallas was comped with 2 $12 dollar vouchers and a crappy hotel. We missed a whole day in Tokyo for our honeymoon and stressed the whole 24 hours. We were supposed to leave at the same time the following day, but that was delayed hours again. And instead of letting the delayed flight go first, they let the flight that was scheduled ahead of us. American should refund us the day wasted in Dallas that should have been in Tokyo! We had lost out on paid events that we can’t get refunded. When we finally did leave, it was a good flight. You would think that was the only issue with American but we from the LAX layover, we were delayed 6 hours and were given a $12 dollar voucher that covered a drink only. The only communication we were given then was that because they were delayed in a prior flight we were delayed again. I don’t understand why it was only with American that we had such a bad time with! They have definitely left a sour taste in our mouths for our honeymoon! And then they did send an email saying we could have 2K miles…. For what? To be delayed into another day and miss our flight again?

The delay was not handled well and the offers to move flights and get travel credit was also not ideal.

The worst seat in any business class. Food are worst then economy class.

No food on 4.5 hour flight, wi-fi did not work. Terrible experience for a long haul flight.

first leg from san diego to chicago, only had cookies for snack. 1 flavor of sparkling water chicago to washington dc had option of cookies, pretzels, or gold fish. had 2 flavors of sparkling water. 2nd flight better however the best part was there was no delays!!! Got to chicago and washington dc early. That was wonderful!!!!

Multiple delays and made us miss the connecting flight and lost our bags

4 hours late, including over +1 hour waiting in plane to take off. Baggage left behind too.

Do a bit better with n first class offer some real food and pillows

It was Christmas and the crew was awesome. And the passengers were patient.
