Where do I return my rental

Whatevr rental car co.( hertz alamo avis.. whatevr name. Take bak to same rental name n drop car off in return lane at air port to whatevr name it is in.... good luck

I actually drove my rental car from Washington DC to Pennsylvania. It was in my rental agreement that I could drop it off at the Philadelphia Airport. You just follow the signs for Rental Returns at the airport and away you go.

The same location where you rented it; rental return area is clearly marked as you enter airport parameter
