Did not like that I cannot check in online if you select you have no bags to check in

Not happy with the flight being delayed then being boarded and having to sit in the small space with no air flowing. It was hot and muggy on the plane until we finally took off. Other than that everything was great. I was just happy it was cancelled cause United usually does that last minute.
