Airline reviews

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.

Everything was good, except the seats in economy were so close together, you could barely get out when the seat in front of your was reclined. If the airlines keep jamming in more and more seats, it will become intolerable. I will look for another airline that considers customer comfort and does not keep adding more rows of seats for more profit.

The flight was canceled the day of the flight. United says it was FAA issue, with some 35 flights canceled and more delayed.

Slight delay but not bad. UA app worked well! Got regular updates of gate changes, etc. Don't have any complaints.

Food is very bad and entertint not too many options ... flight attendet service is not good

One problem, but a serious one - the plane is built with electric windows that tint dark to reduce light. Sitting next to the window is VERY UNCOMFORTABLE as it emits so much HEAT in the face when tinted.

Apparently the WiFi you buy on on one flight doesn't carry on with connecting flights.

I had very little time to change planes originally in Denver after my flight from Omaha. I had an hour and a half layover in Denver originally and my flight leaving Omaha was delayed an hour because they had to change a tire, which I can understand. When I reached Denver my other flight was late, fortunately, but I still had only 10 minutes to run about a mile through the airport to get to my flight. Again, fortunately, I am a healthy 71-year-old and was able to accomplish this feat. However, the stress was more than necessary to bear.

If other people in flight, followed instructions and were much cleaner.

Flight was great. On time. Pleasant crew and responsible passengers. My only disappointment was that there was no coffee or tea offered. It was a short flight but a coffee would have been appreciated for what the price of tickets are now.
