Seems like we are doing the same planning at the same time. I usually go to the AOL Travel site & try Best Fares from your City first. Then I also go to the main website of the Airline we are looking for. At this time, Air Tran and SouthEast Airlines seem to be showing the best non-stop fare for us, that would be either Phila. to Orlando with Air Tran or Allentown to Sanford, Fl with SouthEast Airlines. Good Luck!
