How Much Does BWI Long Term Parking Cost in 2026?

BWI long term parking charges are set at $11 per day as of July 1, 2024, per the Maryland Aviation Administration (MAA). This is the maximum daily rate — you will never pay more than $11 for a single calendar day in the Long Term Lots, regardless of when you arrive or leave. That makes budgeting simple: multiply your number of days by $11.

Before July 2024, the long term rate was lower. The 2024 adjustment was the first parking price increase at BWI since 2009. Revenue from the increase supports terminal upgrades, including the $520 million Concourse A/B Connector that opened January 9, 2026 — the largest capital project in BWI history. The new baggage handling system now processes 3,500 bags per hour, up from 2,100.

Here is a quick multi-day cost breakdown at the on-airport long term rate, next to Doubletree Baltimore, the cheapest lot Triply sells. Doubletree figures multiply its about $6/day rate, so treat them as estimates for any trip that is not seven days.

For a week-long trip, BWI long term parking charges add up to $77 total. That is a straightforward, predictable cost with no hidden fees. A 7-night stay at Doubletree Baltimore is billed as 8 days and checks out at $49.27, still well under a week in the Long Term Lots. See the off-airport lots Triply sells, from about $6/day.

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 rate of $11 per day, per official airport data. The key difference is location and availability. Lot A typically fills first during peak travel periods. If Lot A is full, digital signs at the entrance direct you to Lot B. Both lots are open-air and uncovered.

Because the lots are open-air, weather matters in Maryland. Summers bring heat and humidity; winters bring ice and snow. If covered parking is a priority for you, the airport's Daily Garage ($16/day) and Hourly Garage are covered. None of the lots Triply sells near BWI lists covered parking. For a deeper look at Lot A specifically, see our guide on BWI Long Term Parking Lot A rates and tips.

Both lots have accessible parking spaces for drivers with disability placards or plates. The closest accessible spaces overall are in the Hourly and Daily Garages. If you need accessibility accommodations, arriving early at Long Term Lots A or B is a good idea during busy travel periods.

How Does the BWI Long Term Parking Shuttle Work?

The shuttle is free and runs continuously between the Long Term Lots and the terminal. According to official BWI airport data, the shuttle operates every 10-15 minutes during normal hours. Between 1:00 AM and 5:00 AM, headways extend to approximately every 25 minutes. There is no extra charge — it is included in your $11/day parking fee.

When you arrive, park your car and note your shuttle stop number. This is important. Forgetting your stop number on return is the most common mistake. Take a photo of the signage near your car before walking to the shuttle. The shuttle drops you at the terminal lower level, near baggage claim. From there, follow signs to your concourse.

On your return, find the designated shuttle pick-up zone on the terminal's lower level. Shuttles are clearly marked for Long Term Lot passengers. The ride back to the lots typically takes just a few minutes. For a full step-by-step walkthrough of the return process, see our article on BWI long term parking pick-up.

How Does BWI Long Term Parking Compare to Off-Airport Alternatives?

BWI long term parking charges of $11/day are competitive for on-airport parking nationally, but the off-airport lots Triply sells undercut that rate. Here is how the main options compare:

The off-airport lots Triply sells run shuttles on their own schedules. Doubletree Baltimore runs every 15 minutes most of the day, and the Westin and Sheraton run 24 hours every 30 minutes, with free shuttle service. Country Inn & Suites and Clarion Hotel BWI North have gaps in the day, so plan your flight times around them. The on-airport long term shuttle, at about every 10-15 minutes, runs more often than the 30-minute shuttles at the other lots, but the off-airport lots cost less per day. For the full picture on off-airport options, see our guide to airport parking near BWI.

How Much Can You Save on BWI Long Term Parking for a Week-Long Trip?

For a 7-day trip, BWI long term parking charges total $77 at $11/day. Doubletree Baltimore at about $6/day brings that to about $43, a savings of roughly $34, or about 44%. Over two weeks, the gap grows to about $68 at the same daily rate.

Several of the lots Triply sells sit at hotels: Doubletree Baltimore, Country Inn & Suites, the Westin, the Sheraton and Clarion Hotel BWI North. Triply sells parking only, not rooms, and the Westin and Sheraton both say no hotel stay is required to park. Doubletree Baltimore is the cheapest at about $6/day. For a detailed look at that hotel, see our DoubleTree BWI Airport hotel parking guide.

If you want to keep things simple and stay on-airport, BWI long term parking charges are still among the most affordable on-site options. The Daily Garage costs $16/day and Express Parking runs $14/day — both notably higher than the $11/day long term rate. For trips of 4 or more days, the long term lots are clearly the smart on-airport choice.

How Do You Get to BWI Long Term Parking and Where Do You Pay?

The Long Term Lots are accessible via Interstate 195, the primary airport access road off I-95. Follow signs for BWI Long Term Parking once you exit onto Aviation Boulevard (MD Route 170). Smart parking guidance signs along the entry roads indicate real-time availability. If Lot A is full, digital signs route you to Lot B automatically.

Before you head out, check real-time traffic on Waze — I-195 can back up during rush hour and school pickup times. Allow extra time if you are driving from Downtown Baltimore (about 9 miles north) or Washington, D.C. (about 30 miles southwest). Early morning departures typically see the lightest traffic.

Payment is handled at pay stations when you exit. You can pay with cash, Visa, Mastercard, American Express, Discover, or contactless payment (tap-to-pay). There is no need to pay before boarding the shuttle. The pay stations are located at the lot exits. Keep your ticket from when you entered — you will need it to calculate your total fee.

What Are the Rules and Restrictions for BWI Long Term Parking?

BWI Long Term Lots A and B are designed for standard passenger vehicles. There are restrictions for oversized vehicles — large RVs, commercial trucks, and vehicles that exceed standard height or length limits may not fit in designated spaces. If you drive an oversize vehicle, contact the airport in advance or consider off-airport lots that accommodate larger cars.

The lots are open-air and unsecured in the sense that they are not enclosed garages — but they do feature 24/7 security patrols and surveillance. BWI Marshall Airport operates with approximately 22,000 total parking spaces across all facilities, per official airport data. Long term lot capacity is substantial, but lots can fill during Thanksgiving, spring break, and summer peak weeks.

There is currently no valet parking offered at BWI. All long term parking is self-park. If you are hoping for valet service, check our guide on BWI long term parking valet alternatives for what is actually available. BWI long term parking charges apply from the moment you enter the lot — there is no grace period beyond what is included in the daily cap.

Is It Worth Booking BWI Long Term Parking in Advance?

On-airport Long Term Lots A and B currently operate on a first-come, first-served basis — there is no advance reservation system for the official lots as of June 2026. You simply drive in and take an available space. This is convenient, but it means there is no price guarantee or spot guarantee during peak travel periods.

Off-airport lots on Triply, on the other hand, can be booked in advance, with free cancellation with a full refund up to 24 hours before check-in, so there is little risk. BWI long term parking coupons and pre-book deals are another way to cut costs before you travel.

If you are flying during a major holiday or summer peak week, booking an off-airport lot in advance is the safest move. It holds your space at the rate you booked. Search and reserve BWI parking from about $6/day on Triply and compare the lots side by side before your trip.

Tips for Reducing Your BWI Long Term Parking Charges

• Book off-airport in advance. Doubletree Baltimore starts at about $6/day, roughly 44% less than the on-airport long term rate.
• Pick a hotel lot that fits your flight. Doubletree Baltimore runs a 24-hour shuttle, and the Westin and Sheraton run free 24-hour shuttles, while Country Inn & Suites and Clarion have gaps in the day.
• Enroll in TSA PreCheck. Faster security means you can arrive later, cutting into your paid parking time on departure day. Learn more at TSA PreCheck enrollment.
• Note your shuttle stop number. This prevents delays on return and keeps your total parking time accurate.
• Avoid the Daily Garage for long trips. At $16/day versus $11/day for Long Term, the Daily Garage costs 45% more for the same trip length.
• Check promo codes before booking. See our guide on BWI long term parking coupons for current deals.
• Travel light on your first day. Arriving before peak hours (before 7 AM or after 9 PM) means smoother lot entry and faster shuttle boarding.

BWI long term parking charges are straightforward at $11/day on-airport, but the real savings are available if you plan ahead. Off-airport lots on Triply from about $6/day, with shuttles every 15 to 30 minutes during service hours, are a genuine alternative, not a downgrade. Find and compare BWI parking across the lots on Triply, with rates from about $6/day.
