I'm already planning a trip to WDW for next June and USAir is all we have here in Pittsburgh. I was hoping to use DH's freq. flyer miles to get 2 tix free (we need 4), and I need to book the flights soon so there are some "free" seats left on the plane. And of course, to hold your seats you have to pay in full, so I'm worried about losing $$ if USAir isn't around next summer.
