United leg room, even in economy seating, is plenty roomy. Couple problems: I requested wheelchair assistance, which we needed in SanFrancisco and Las Vegas, but we never got it. Outbound Flight in Las Vegas was at 5:30 and we were told to be at the airport 2 hours early. The problem is, United employees do not start work until 4 AM and many of the self bagging machines were not working. Then TSA doesn't open up that early and pre check wasn't open. All of this meant more stress on teh traveler than necessary as many United travelers were rushing to try and get all taken care in order to make the flight on time.
