For the full breakdown of all pricing tiers, see our guide to Baltimore Washington Airport parking rates for 2026.

Where Are BWI Long Term Parking Lots A and B Located?

Long Term Lot A and Lot B are located on the south and west sides of the BWI terminal campus, accessible via Aviation Boulevard (MD Route 170). Both lots are open-air, surface-level, and well-lit. Follow signs from the main terminal roadway — dedicated signage guides you to Long Term from all major airport entry points.

The primary access road to BWI is Interstate 195, which connects directly to Interstate 95. Drivers coming from Annapolis use Interstate 97, and those from D.C. typically take the Baltimore-Washington Parkway (MD-295). Before you leave, check real-time traffic on Waze — especially during morning rush hours when I-195 can back up.

Once parked, note your lot section and row number. The Long Term lots use numbered shuttle stops — note your stop number before walking away from your car. The shuttle will return you to that same stop when you land.

How Does the BWI Long Term Parking Shuttle Work?

The free BWI shuttle picks up at numbered stops throughout Long Term Lots A and B and drops you at the terminal's lower level. Shuttles run every 10-15 minutes during normal operating hours, and every 25 minutes between 1–5 AM, per official BWI shuttle data.

The shuttle is free — no tip required, no separate ticket needed. Just board at your numbered stop and tell the driver if you have oversized luggage. On your return, pick up the shuttle from the ground transportation level at the terminal. It will loop back to your lot.

How Do You Reserve BWI Long Term Parking in Advance?

Triply does not sell the airport's own Long Term lots, but you can reserve an off-site lot near BWI on Triply ahead of time, from about $6/day. Booking ahead holds your spot, and bookings come with free cancellation with a full refund up to 24 hours before check-in.

Here's how to reserve in three steps:

1. Search your dates on Triply's BWI parking search: enter your arrival and departure dates to see live pricing.
2. Compare the five off-site airport lots by price, distance and shuttle hours, and check the on-airport Long Term rate of $11/day for reference.
3. Book and save your confirmation. Doubletree Baltimore, Country Inn & Suites, Sheraton Hotel and Clarion Hotel BWI North all have you check in at the front desk on arrival, so keep it handy.

Advance booking matters most around Thanksgiving, Memorial Day weekend, July 4th, and the last two weeks of August. During these periods, Long Term lots can reach capacity by mid-morning. If you're planning a summer trip, don't assume space will be available when you arrive.

What Should You Do If BWI Long Term Parking Is Full?

If BWI Long Term Parking is full, your best immediate alternatives are the BWI Rail Station Garage ($12/day) or Express Parking ($14/day) — both offer free shuttles and are rarely at capacity when Long Term lots fill up.

Here's your priority order if Long Term is showing full:

• BWI Rail Station Garage ($12/day): Just $1/day more than Long Term. Free shuttle to the terminal runs 24/7.
• Express Parking ($14/day): Located near the Cell Phone Lot on Scott Road. Free shuttle included.
• Off-site lots on Triply (about $6 to $8/day): Doubletree Baltimore, Country Inn & Suites, The Westin, Sheraton Hotel and Clarion Hotel BWI North are all cheaper than Long Term. Availability shows when you search.
• Daily Garage ($16/day): On-airport fallback if you need to park immediately with no advance search time.

The safest move is to book off-site before you arrive. Bookings on Triply come with free cancellation with a full refund up to 24 hours before check-in, so you lose nothing by booking early.

Tips for a Smooth BWI Long Term Parking Experience

A little preparation goes a long way at BWI Long Term Parking. These tips are based on current lot conditions and traveler reports as of 2026:

• Photo your row and stop number the moment you park. Long Term lots are large and every row looks the same when you return tired.
• Add 20-30 minutes to your departure window. Factor in the shuttle wait (up to 15 minutes) plus the ride time plus clearing TSA security screening.
• Check availability online before you leave home. The BWI Long Term Parking page shows live capacity percentages.
• Enroll in TSA PreCheck if you haven't already. TSA PreCheck cuts security time significantly, which is especially useful when you're already adding shuttle time to your commute.
• Book ahead when possible. Reserving an off-site lot on Triply holds your spot at the rate you booked, with free cancellation with a full refund up to 24 hours before check-in.
• Bring your parking ticket with you. If you lose it, be prepared for potential delays at the exit gate. Our sibling article on BWI long term parking lost and found explains exactly what to do if a ticket goes missing.
• Use contactless payment at exit gates to speed up checkout. All major cards and mobile pay are accepted.
• For peak travel dates, book at least two weeks in advance. Thanksgiving and the July 4th window are the highest-demand periods at BWI.
