1. Everything was satisfactory concerning the flight. 2. Can't think of what could be better right now.

Entertainment kept turning itself off. Gave up on watching a movie.

Both of my flights arrived early and check in process was smooth

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

Not United Airlines' fault. It's ORL airport's fault.

United overall experience is great these days. Airport experience was very organized. Staff on flight were great. App and information as good as it gets.

Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint

Flight home lot's of room shame I never noticed that they ripped my suitcase and didn't notice it to I got toy destination and had to buy new set

It was delayed several hours which delayed our connection in Denver. Not happy.

Ridiculous delays with weak excuses. United needs to do their job and troubleshoot. The rate they charge demands no less. Planes are way too full and seats are cramped. Charging for seats and luggage adds insult to injury.
