Baltimore/Washington (BWI) Airport Parking Guide
By ParkON Team | Last updated: April 2026
Baltimore/Washington International Thurgood Marshall Airport (BWI) serves the Baltimore metro and much of the greater Washington, D.C. region. It's a Southwest Airlines focus city with plenty of capacity and a broader parking footprint than either DCA or IAD nearby. BWI offers hourly and daily terminal garages, the Express Parking lot, the Long-Term Parking lots, and several off-airport options bookable through ParkON with free shuttle service. Off-airport parking near BWI starts from as low as $8/day when you pre-book through ParkON.

Why Pre-Book BWI Parking
BWI is busiest on Monday mornings, Thursday and Friday evenings, and around major holidays. The Hourly and Daily Garages fill first because they're walking distance to the terminal; the Express and Long-Term lots handle overflow and multi-day trips with a free shuttle. Off-airport lots beat even the Long-Term Parking rates on a per-day basis and offer comparable shuttle service.
Pre-booking locks in a guaranteed spot and a published daily rate, typically well below the drive-up price. Off-airport options can be reserved in minutes through ParkON's BWI search.

On-Airport Parking at BWI
BWI's on-airport rates are set by the Maryland Aviation Administration and updated periodically. Always confirm on the official BWI parking page before your trip.
Hourly & Daily Garages
BWI's Hourly Garage is directly across from the terminal, making it the fastest option for drop-offs and short pickups. The Daily Garage is also walking distance — ideal for 1–3 day trips where shaving a few minutes at drop-off and return matters. Both are premium-priced for proximity.
Express Parking
The Express Parking lot sits a short shuttle ride from the terminal and is priced between the Daily Garage and the Long-Term Parking lots. For 3–5 day trips it's often the best on-airport compromise between cost and convenience.
Long-Term Parking
BWI's Long-Term Parking lots offer the lowest on-airport daily rate, served by a continuous free shuttle. They're the right choice if you prefer to stay on airport property for a week or longer.
Off-Airport Parking Near BWI
Independent and hotel-based off-airport lots near BWI offer the lowest rates around the airport and include free shuttle service to the terminals. Travelers who pre-book off-airport typically pay 40–60% less than the on-airport Daily Garage, with options starting from $8/day through ParkON.
Popular off-airport lots bookable through ParkON include:
- Marriott BWI Airport — hotel parking with free shuttle; indoor lobby wait area; hotel amenities access.
- Westin BWI Airport — hotel lot with shuttle service; close to the airport; modern facility.
- BWI Speedy Park — dedicated parking operator with competitive daily rates and free shuttle.

BWI Cell Phone Lot & Pickup Tips
BWI has a free cell phone waiting lot for drivers picking up arriving passengers. You can wait there at no charge until your traveler is ready, then drive directly to the arrivals curb. Signage off the airport access road points the way.
Avoid circling the terminal roadways — airport police keep curbside traffic moving, and the cell phone lot is both calmer and cheaper than waiting in active traffic lanes.
Getting to BWI
BWI sits roughly 10 miles south of downtown Baltimore and about 30 miles northeast of Washington, D.C. Primary access is via I-195, which connects directly to I-95 (Baltimore to D.C. corridor) and the Baltimore-Washington Parkway (MD-295). The airport is also served by the BWI Rail Station on the MARC Penn Line and Amtrak, with a free shuttle between the station and the terminal.
Friday evening traffic on I-95 between D.C. and Baltimore can be heavy; for Friday departures give yourself more runway than you would mid-week.
Booking, Cancellation & Arrival Tips
- Book ahead. Both on-airport and off-airport rates are lowest when reserved in advance. Walk-up travelers pay the highest price — and risk finding the Daily Garage full during peak periods.
- Budget for the full stay. Off-airport lots bill by the day with a 1–2 hour grace period. A 49-hour stay counts as 2 days; a late return is settled at the lot gate at that lot's posted rate.
- Plan shuttle time into your arrival. ParkON recommends being at your parking lot at least 30 minutes before the time you'd like to be inside the BWI terminal.
- Flexible cancellation. Most ParkON reservations can be cancelled for a full refund up to 24 hours before your scheduled arrival. Cancellations inside 24 hours are refunded minus the service fee; no refund after your scheduled arrival time. See cancellation details for the full policy.
- ParkON is an independent reservation service. We don't operate shuttles or lots — we help you compare, reserve, and save at trusted off-airport facilities near BWI and across the country.
