6.8 Okay
MCO-EWR
Pros:The crew was excellent - courteous/aware/friendly. The flight, although 2 hours delayed (9;20pm scheduled departure) was pleasant and smooth. Also, the de-boarding process was surprisingly quick.
Cons:A 2 hour delay at 9:20pm at night is unfortunate yet frustrating experience, especially when we moved our flight up due to a travel warning for EWR (ironically enough, our originally scheduled flight (1922 MCO-EWR). I'm giving an overall OK (instead of good) due to the fact that there were no snacks (although I did not want anything, it didn't go unnoticed) and although there was free inflight entertainment for personal devices, I feel the passengers should have been given free internet access - in my opinion, it would have been the appropriate thing to do. In any case, this experience doesn't change my positive opinion of United.

4.6 Mediocre
BOS-SFO
Cons:The first contact in the airport was quite rude when informing me that I had to measure my suitcase for size. I have carried this suitcase on on every airline for over 10 years....the size got smaller and United got $25.00....not happy. There was NO free movies, no access to TV, flight pattern....nothing and it could not be turned off. ONE cookie for a coast-to-coast flight. What happened to United?
