Other Car Rental Programs/Partners (ie. Alamo, Enterprise, Sixt) - PHL Fleet

Is Alamo at PHL an Alamo/National Combo. The reason I'm asking is that I'm picking up a luxury class car next month and while Alamo considers a Park Avenue a luxury, which I don't, National offers a Deville. So I'm figuring if it's a combo location, I'm safe in getting a Deville. Sound reasonable?

Hi folks...

The date is drawing near and was still wondering if anyone has had experience with this at this location.

Thanks!
