While this is not a consolation, United at least is making an effort. I purchased an online ticket on the UAL website today for my sister. After purchasing the ticket, I realized that I had her going out the wrong day of the week. I wasn't too terribly concerned about the $75.00 change fee, as this was a work related business trip.

After making the changes, the reservationist never asked for a credit card number for the change fee, which I thought was odd, so I asked about it - I was trying to be honest. She indicated that about a year ago, they did away with the $75.00 change fee for any changes made to a ticket within 24 hours of purchase. While most of us may make changes later on during a trip, it was nice this change benefited me, and others who were able to catch a mistake, or make changes within the timeframes imposed.
