6.8 Okay
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.
A
4.6 Mediocre
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?

Pros:Amazing crew
Cons:Tight seats, no access to actual WiFi unless you purchase a yearly or monthly plan
S
4.6 Mediocre
Pros:Ordered the Protein Box, it was ok.. crew members nice.
Cons:The Smell on the flight was unacceptable, I was sitting about a couple rows across the middle bathroom, and it smelled horrible, I had never had an experience like this on any other flight, I fly United many times a year, and this had me really uncomfortable for almost 5 hours, since the flight was delayed almost 1.5 hours while we sat onboard the aircraft at the gate, that had me miss dinner plans too in San Francisco as well. I really hope they can fix that, For the good of the passengers, felt like I was going to be nauseous all the time, and I'm really not someone that complains or takes time to review badly.
N
4.6 Mediocre
Cons:2.5 hour delay. No working bathrooms. Couldn't hear the tv and headphones that they gave out were useless.
A
2.0 Poor
Cons:Purchased tickets 4 months before this flight for a departure time of 6:05pm. Tried to check in and check baggage at 9:30am but was turned away saying I could only check in 3 hrs prior to my flight. Came back at 3:00pm to check-in and they could not find my information. An hour later they find out that they cancelled the flight and moved my departure time to 8:25am for that day. They say they emailed 3 times in May but I never got it (I'm a bit crazy about my email staying clean) so they say it might have went in to my spam folder due to they types of emails they send to customers. They only kept repeating that they notified me so there is nothing they could do. I ended up going to Air Canada to get a flight to PHX the next day. No apology, no help, no hotel for the night...Terrible experience by United. They gave me a customer relations group contact information to follow up with for complaint but since they sent me the 3 emails in May about the change, they have no liability to fix the situation.
A
2.0 Poor
Cons:Departure was delayed. No explanation. The boarding area is crowded and confusing. The plane's bins were too small for roller boards so passengers had to carry bags outdoors in snow and terrible wind, to get them loaded. The Newark airport where the plane landed was miserable! Departure from Newark was worse than landing if that could be possible! Awful!
