We will be returning a rental car to Malpensa very early in the morning to make a 6:20 am flight. Is the rental return lot for the major companies close to the terminal to allow for walking or is it customarily reached by a shuttle? If the latter , I doubt the rental office will be open nor would there be a shuttle running and I'd have to accomplish the return the evening before and use early morning hotel shuttle service. Anyone familiar with these logistics. Thanks.
The rental return for most agencies is in the parking garage across the street from the terminal. Very close and walkable.
To drop before opening hours, just leave the keys and your completed drop-off form in the key drop of the booth in the parking garage. I take the precaution of photographing the car from all angles in case there is a dispute about its returned condition. But I've never had a problem. Oh, and fill up on the Autostrada before you get to the airport. Doing so in Somma Lombardo can be a hassle.
