I booked air for my parents and my family last month thru southwest. Prices have dropped and I am going into change the flight to get the lower fare and notice I can only do it for the whole reservation. I booked all 6 on one reservation going down and then separate coming back. My mom has had some health issues and one of the reasons we booked swa was that I knew we could cancel, but get credit for future travel. BUT, now I am concerned I would have to cancel all our reservations and just rebook ours. How would it work? Has anyone had to do this? Would I be able to cancel just hers and my dad's and not our (4) ressies? Someone please put my mind at ease. The fares were not cheap.
