Keep in mind, I've never flown (and won't this time earlier) but my aunt is trying to fly out Kalamazoo to Orlando, and it seems just about every flight Orlando to Chicago, or whatever connecting flight back to Kalamazoo seems to be full (even though some are still offering the rate/flight) .. is this usual? Could seats open up in the near future? why are they still offering the flights? any insight is welcomed, ty!
