I'm with TropicalFlyer. I use a travel agent (actually four of them) at IAPA and have been real happy. One did book a car for me at Atlanta when I was going to Houston (connecting in ATL) one time, but she caught the mistake and fixed it before I saw it. Anyone who's not an IAPA member and might want to join, let me know. I get miles for signing you up. They're also good on miles: 1 per dollar on tickets they sell, plus 50 per hotel or car reservation. Good on any airline.
