I purchased 4 round trip tickets from Dallas to MCO about 6 months ago, got what I think is a good price $104.00 each. I used travelocity and these are with United. They are all in my My familys names. The problem is my son may not be going, he kind of wants to go to summer school and work at his new job.(I think he is my son) LOL But my mother in law wants to go if he doesn't . Do you think she would be able to use his ticket? She doesn't have a problem with coming down at a different time and getting her own airfare, but I was just wondering if there is anything I can do with his ticket if I don't decide to "make" him go. Beverly, are you or any of the other resident experts out there? Thanks in advance!! P.S. These are non-refundable.
