Same idea as Long Term A — remote, cheaper, shuttle required.
B is the other half of the remote field. If A is Full on Sunday night, B is often the lot that still has rows. Do not drive to Hourly “just to see” when you already know you are gone a week.
Covered garage on the terminal — the closest drive-up at BWI.
Covered overnight parking with a frequent shuttle to the curb.
A smaller lot with a free shuttle and a price between Daily and Long Term.
The cheaper remote lots — same rate as B, different field.
Trips of several days when A is full.
Free shuttle, 24/7.
About $11 a day. Confirm the rate on the gate sign — posted prices move.
Limited means you may still find a space if you circle, but another lot is the safer call. Full means that lot is not taking drive-up cars. Use the live board and pick the next BWI lot instead of waiting in the inbound loop.
