A daily garage a few minutes further away from the drop-off point is well-serviced by complimentary shuttle buses. It also offers an hourly fee with a reasonable daily limit, so it is ideal for trips of a few days or more in length.
Both hourly and daily garages feature electric vehicle charging stations and a useful Smart Park system where displays tell you how many spaces are available and where, so you can get parked quickly.
Beyond the daily garage are the express and economy parking lots, both of which have typically low daily rates and free shuttle bus services.
All these on-site parking options are provided directly by BWI Airport and include complimentary services such as jumper cables, tire changes and accessing locked cars for all customers.
