Back to Baltimore Washington Airport Parking Rates 2026: Full Guide | Complete BWI Airport Parking Guide

BWI long term parking is the most affordable on-airport option at Baltimore/Washington International Thurgood Marshall Airport, priced at $11 per day as of July 1, 2024, per the Maryland Aviation Administration (MAA). The BWI long term parking garage rates apply to two open-air lots, Lot A and Lot B, both served by a free shuttle running every 10-15 minutes. If you want to spend less, Triply sells five off-site airport lots from about $6/day, which is up to 44% less than the on-site long term rate.

• Current long term rate: $11/day (effective July 1, 2024, the first rate increase since 2009)
• Two lots available: Long Term Lot A and Long Term Lot B, both open-air and self-park
• Free shuttle: Runs every 10-15 minutes (every 25 minutes between 1-5 AM) from both lots to the terminal
• Off-site savings: Triply sells five airport lots from about $6 to $8/day, roughly 24% to 44% less per day than the $11 long term rate
• Total on-airport capacity: Approximately 22,000 spaces across all BWI facilities
• New in 2026: The $520 million Concourse A/B Connector opened January 9, 2026, and smart parking guidance systems are also being rolled out

How Much Do BWI Long Term Parking Garage Rates Cost in 2026?

BWI Long Term Parking costs $11 per day, per official MAA published rates (verified June 2026). There is no weekly cap or multi-week discount — the rate stacks at $11 for every calendar day your vehicle is parked.

These rates took effect on July 1, 2024 — the first increase since 2009. For context, the long term rate held at the same price for over 15 years before this adjustment. The MAA cited aging infrastructure improvements and funding for capital projects — including the now-completed $520 million Concourse A/B Connector — as key reasons for the update.

Here is a side-by-side view of the on-airport options and the five airport lots Triply sells, so you can see where the long term lots sit in the pricing ladder. Triply rates are for a 7-day stay booked ahead and change by date.

For a deeper look at how these rates have changed over time, see the full breakdown in our BWI long term parking price increase guide.

What Is the Difference Between Long Term Lot A and Lot B at BWI?

Both Long Term Lot A and Long Term Lot B charge the same $11/day rate. The main difference is location — Lot A sits closer to the main terminal approach, while Lot B is positioned further along the lot road. Both are open-air, self-park, and share the same free shuttle system.

The lots together account for a large share of BWI's roughly 22,000 total on-airport parking spaces, according to official airport data. Accessible parking is available in both lots. That said, the closest ADA-accessible spaces to the terminal are in the Hourly and Daily Garages, which offer a covered, shorter walk if you have mobility needs.

One practical note: both lots can fill during peak travel windows — think summer Fridays, holiday weekends, and spring break week. If you arrive and find one lot full, airport staff typically direct overflow to the available lot. Booking in advance through the BWI reservation system removes that uncertainty.

How Does the BWI Long Term Parking Shuttle Work?

The free shuttle runs every 10-15 minutes between Long Term Lots A and B and the main terminal, according to the BWI Marshall Airport shuttle page. Between 1–5 AM, service slows to every 25 minutes — so factor that in if you have a very early departure or a late arrival.

Here is what to expect, step by step:

1. Park your vehicle and note your lot letter (A or B) and the nearest numbered shuttle stop sign.
2. Walk to the nearest marked shuttle shelter — stops are numbered and clearly signed throughout both lots.
3. The shuttle arrives and takes you directly to the terminal's lower level arrivals area.
4. On return, board the shuttle at the dedicated Ground Transportation area on the terminal's lower level. Tell the driver your lot and stop number.

Pro tip: Take a photo of your stop number before walking to the terminal. After a long trip, it is easy to forget whether you parked at Stop 3A or Stop 5B. This simple step saves real time on return.

The shuttle also connects to Express Parking, the Daily Garage, and the BWI Rail Station — all on the same free network. Smart parking guidance systems are currently being rolled out across on-airport facilities, which should eventually give real-time shuttle arrival estimates at each stop.

On-Site Long Term Parking vs. Off-Site Lots: Which Saves You More Money?

All five airport lots Triply sells cost less per day than BWI's on-airport long term rate. The gap is meaningful for longer trips. Here is what a 7-day trip looks like:

• 7 days in BWI Long Term: $77
• Doubletree Baltimore: about $43 for 7 days (about 44% less)
• Country Inn & Suites and The Westin: about $51 for 7 days (about 34% less)
• Sheraton Hotel: about $53 for 7 days (about 31% less)
• Clarion Hotel BWI North: about $58 for 7 days (about 24% less)
• Real 7-night checkouts on Triply run $49.27 to $66.78 (8 billed days, no tax added), still below a week in Long Term

Shuttle service varies by lot. The on-airport long term shuttle runs about every 10 to 15 minutes. Doubletree Baltimore runs every 15 minutes from 5 AM to midnight and every 30 minutes overnight. The Westin and Sheraton Hotel run free shuttles 24 hours, every 30 minutes. Country Inn & Suites and Clarion Hotel BWI North have gaps in service (none noon to 4 PM at Country Inn, none 10 AM to 5 PM at Clarion), so check your flight time before you book.

Rideshare break-even check: An Uber or Lyft to BWI from a nearby area like Linthicum or Glen Burnie typically runs $15–$25 each way, based on typical market rates. A round trip costs $30–$50. For any trip longer than 3 days, the BWI long term lot at $11/day is already cheaper than a single round-trip rideshare. For longer trips, the savings compound quickly.

Before you drive, check real-time traffic on Waze — especially on weekday mornings when I-195 and I-95 can back up near the airport exit.

How to Get to BWI Long Term Parking: Directions from I-95, I-95, and I-195

Long Term Lots A and B are accessed via the main airport loop road off MD Route 170 (Aviation Boulevard). All three major highway approaches funnel into the same route. Here are the key directions by origin:

• From I-95 North or South: Take Exit 47A onto I-195 East. Follow I-195 to MD Route 170 (Aviation Blvd). Follow airport signs toward Long Term Parking.
• From I-695 (Baltimore Beltway): Take Exit 4A onto I-195 East toward BWI. Then follow MD Route 170 to the airport loop and Long Term Parking signs.
• From Baltimore-Washington Parkway (MD-295): Take MD Route 176 (Dorsey Road) westbound, then connect to Aviation Blvd heading toward the terminal. Follow Long Term Parking signs.
• From Annapolis / I-97: Take I-97 North to I-695, then I-195 East as above.

Once on the airport loop road, Long Term Lot A appears first. Lot B follows shortly after. Both are clearly signed. Payment happens at automated exit stations — cash, Visa, Mastercard, Amex, Discover, and contactless payments are all accepted.

How to Reserve BWI Long Term Parking in Advance

Booking ahead locks in your spot and can help you avoid sold-out conditions during peak travel weeks. BWI's parking reservation system allows advance booking through the official airport website. Triply sells off-site airport lots near BWI, not the airport's own lots.

Here is how to book step by step:

1. Visit the BWI Long Term Parking page on the official airport website.
2. Enter your travel dates and select Long Term Lot A or Lot B.
3. Complete payment online. You will receive a confirmation with a QR code or reservation number.
4. On arrival, use the dedicated reservation lane at the lot entrance.
5. On departure, exit using your confirmation, with no surprises at the pay station.

Advance booking matters most around Thanksgiving, Christmas, New Year's, Fourth of July, and summer peak season (mid-June through mid-August). During those windows, travelers frequently report both Long Term lots filling by mid-morning. If the lots reach capacity, airport staff typically redirect vehicles to Express Parking or suggest off-site alternatives — neither of which is ideal after a long drive in.

If you would rather skip the airport lots, Triply sells five off-site lots near BWI from about $6/day, with free cancellation with a full refund up to 24 hours before check-in. Search BWI parking on Triply to check availability and lock in your rate before peak dates sell out.

BWI Long Term Parking Tips: What to Know Before You Go

These practical details make a real difference — especially if this is your first time using the long term lots at BWI.

• Note your stop number: Every shuttle stop in the lot is numbered. Photograph the sign before you walk to the terminal. On return, tell the shuttle driver your lot letter and stop number for a direct drop-off.
• Arrive with buffer time: The shuttle adds 10-20 minutes to your terminal travel time. Factor that in when planning your departure from home. Also account for TSA security screening wait times once inside.
• Overnight safety: Both Long Term lots are open-air with 24/7 activity from the shuttle operation. They are standard airport surface lots, well-traveled but not enclosed. If covered parking matters to you, the BWI Hourly Garage and Daily Garage are the covered on-airport options.
• EV drivers: EV charging is available on-airport. For off-site lots, check availability directly with the operator before booking.
• Oversized vehicles: Standard parking stalls accommodate most passenger vehicles and small SUVs. Very large trucks or vehicles with roof racks should contact BWI parking operations directly to confirm clearance.
• Payment at exit: Pay stations accept cash, all major credit cards, and contactless payment. There is no pre-pay requirement for walk-up parking, but reservations are recommended during peak periods.
• TSA PreCheck: If you are a TSA PreCheck member, security lines at BWI move significantly faster. This means you can cut your total terminal time and feel less rushed even with the shuttle ride factored in.
• New in 2026: The $520 million Concourse A/B Connector opened January 9, 2026. Southwest Airlines passengers moving between Concourses A and B no longer need to backtrack through the main terminal, a meaningful time-saver once you are past security.
