JET BLUE. When we flew from MD to FL, we would check to get the lowest fares .. and that was about 4 years ago. At that time, Jet Blue was had the lowest and also a direct flight from BWI to West Palm or to Orlando. They were a friendly bunch of people. I remember being held up in Orlando trying to get back to Baltimore and there happened to be a snow storm that hit Baltimore. It was thought that we might have to have a lay over in North Carolina somewhere but the pilot(s) and the control center in Baltimore felt he could make it .. and WE DID. We were the only airline flying in that evening. Had no problem landing either. I think we were served peanuts and something to drink. But the airfare was "cheap." You can make your reservations online or by phone. Nice and clean airline too.
