Thanks for the excellent advice. You guys went through the same thought process that I did- first "make it easy" and then I thought "he can learn much if the flight is delayed or cancelled"." When I realized that BA was still offering the AARP discount and logged in, I discovered that there was a great price on an E+ seat via DFW on the way out. Also got a great price on E+ return from PAR-LHR-MSY on our soon to begin LHR to MSY direct. I gave him the option of traveling via MIA in E (no cheap E+ option on that flight) or via DFW on E+ with the understanding that delays are more likely that way. He chose the more comfortable flight and will risk it. He is 21 years old and can certainly handle it.
