Can anyone advise me on internal flights. My son is currently working in Philadelphia, and wants to visit us in Florida in Sept. He wishes to fly into Orlando or tampa. Due to the fact that he is working in the middle of nowhere, with very little internet access, it's not possible for him to pre-book flights.

Can he just turn up and fly? I have looked at some websites and the prices look around $200 for a return trip, is this about right?

I would book flights from this end and print off and post his tickets, but he's not sure of the exact dates that he will be able to join us

Any help appreciated.

Sue
