Returning a rental car to Miami International Airport (MIA) in 2026 requires heading to the dedicated Rental Car Center (RCC), located at 3900 NW 25th Street. You should follow the clear "Rental Car Return" signs as you approach the airport via Le Jeune Road or the Dolphin Expressway. Most major agencies (Avis, Hertz, Enterprise, etc.) have their return bays on Level 2 or 3 of the RCC. Once you have parked, recorded your mileage, and handed over the keys, you will proceed to Level 4, which houses the rental counters and the MIA Mover station. This automated, 24-hour tram provides a free 4-minute ride directly into the airport’s main terminal. It is a peer-to-peer essential to allow an extra 20–30 minutes for the return process, as the walk from the garage to the tram and the subsequent ride can take longer than expected during peak Miami traffic hours.
