At $11 per day, your total BWI long term parking cost per day adds up quickly on longer trips. The table below shows your total cost at the on-airport rate alongside the cheapest available off-airport alternative.

On a two-week trip, choosing an off-airport lot over the on-airport Long Term option saves you nearly $50.

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

Both Long Term Lot A and Lot B charge the same $11/day rate and are served by the same free shuttle system. The key difference is their physical location on the airport grounds, which affects walk distance and shuttle stop sequence.

Both lots are open-air surface lots — uncovered with no protection from rain or sun. Accessible parking spaces are available in both lots. For a detailed breakdown of each lot's layout and exact location, see our dedicated guide to BWI Long Term Parking Lot A: 2026 rates and tips.

How Does the BWI Long Term Parking Shuttle Work?

The free shuttle is the main connection between Long Term Lots A and B and the BWI terminal. According to official BWI airport data, the shuttle runs every 10-15 minutes during normal hours, and every 25 minutes between 1 AM and 5 AM.

Here is what to expect step by step:

1. Park your car and note your spot number and lot letter (A or B).
2. Walk to the designated shuttle pick-up area in your lot.
3. Board the free shuttle — no ticket or payment needed.
4. The shuttle drops you at the terminal departures level.
5. On return, pick up the shuttle at the Ground Transportation area on the terminal's lower level.

The shuttle also connects to Express Parking, the Daily Garage, and the BWI Rail Station — all on the same free system. For full details on shuttle pick-up zones and return procedures, our guide to the BWI long term parking shuttle pick-up covers every step. Plan to arrive at your lot with enough time before your flight — allow at least 30-40 minutes before your target security arrival time to account for parking, the shuttle ride, and any wait at the stop.

Is BWI Long Term Parking Cheaper Than Off-Airport Parking?

No — off-airport lots near BWI are generally cheaper than the on-airport Long Term rate. Based on current verified rates, the three lowest-priced off-airport options all undercut the $11/day Long Term rate significantly.

Off-airport lots like The Parking Spot (East), The Parking Spot (West), and FastPark 2 all offer the same free 24/7 shuttle service — and their shuttles actually run more frequently (every 5-10 minutes) than the on-airport Long Term shuttle. FastPark 2 is just a 2-minute shuttle ride away and offers covered parking at $7.50/day — a hard combination to beat. Based on our analysis, choosing an off-airport lot over Long Term Lots can save travelers up to 32% on a week-long trip.

How to Save Money on BWI Long Term Parking

There are several practical ways to reduce your BWI long term parking cost per day, whether you stick with the on-airport lots or go off-site.

• Book off-airport: Lots like The Parking Spot and FastPark start at $7.50/day — already $3.50 less per day than on-airport Long Term rates.
• Use promo codes: Off-airport providers frequently offer first-time discount codes or seasonal deals. Check our BWI long term parking coupon guide for current verified deals.
• Pre-book your spot: Locking in a rate in advance protects you from last-minute price spikes, especially around holidays.
• Compare on Triply: Search all BWI parking options on Triply to see live rates side by side in under a minute.
• Consider a park-sleep-fly package: Hotel lots like the DoubleTree by Hilton BWI Airport offer $7.95/day parking with a free shuttle — sometimes cheaper than stand-alone off-airport lots when you factor in a night's stay.
• Avoid the Hourly Garage: At up to $30/day, the Hourly Garage costs nearly three times the Long Term rate for stays over a day.

If you have TSA PreCheck, you can also shave time off your airport arrival — meaning you do not need to arrive as early, which can reduce same-day parking decisions made under pressure.
