I have a full size SUV (website says Ford Expedition) reserved at TPA. When I called the airport location to ask a question about my reservation, the greeting stated "Budget and Avis Car Rentals."

I'm also a member of Budget's Fastbreak and I have this SUV reserved under my Fastbreak account. My question is if Budget and Avis are working together, is there a chance I may get an Avis full size SUV (Yukon) instead of the Expedition?
