You've been there. You're standing under those massive fluorescent lights at 5:30 AM, clutching a lukewarm Starbucks, staring at a screen. Baltimore/Washington International Thurgood Marshall Airport—everyone just calls it BWI—is a weirdly shaped horseshoe. It looks simple on paper, but if you don't have a solid map of baltimore washington airport burned into your brain, you’ll end up walking three miles in the wrong direction.
Honestly, BWI is actually one of the easiest "big" airports to navigate once you realize it's basically one giant loop. But the layout has changed a lot lately. With the recent opening of the A/B Connector and new baggage systems, the way you moved through the terminal two years ago isn't exactly how it works today in 2026.
The Horseshoe Layout: Where Everything Actually Is
BWI isn't a "terminal" airport in the sense of having separate buildings like Dulles or JFK. It’s one continuous building. You’ve got five concourses: A, B, C, D, and E.
If you’re flying Southwest, you’re basically living in Concourses A, B, and C. They dominate this place. If you're on a "legacy" carrier like Delta or United, you're headed to Concourse D. International flights? That’s Concourse E.
Breaking Down the Levels
- Upper Level: This is where the magic (and the stress) happens. Ticketing, security, and all the gates.
- Lower Level: This is purely for baggage claim and ground transportation. If you’re looking for a taxi or the light rail, go down.
The most important thing to know about the map of baltimore washington airport is that Concourses A, B, and C are all interconnected behind security. You can walk from Gate A1 to Gate C14 without ever seeing a TSA agent again. This is a lifesaver if you have a long layover and want better food options, but it's a hike. We're talking 15-20 minutes of power walking.

Security Checkpoints: The Secret to Shorter Lines
People mess this up constantly. They see a long line at Checkpoint A and just stand there like statues.
Don't do that.
Because Concourses A, B, and C are connected, you can use any of those three checkpoints to get to your gate. If Checkpoint A is backed up to the sidewalk, walk five minutes down to Checkpoint B or C. Usually, one is significantly shorter.
Pro Tip for 2026: Checkpoint B is the only one open 24 hours. If you have a weirdly early flight or a late-night arrival where you need to get back into the secure area, head to B.

The D/E Checkpoint is its own beast. It serves the "everything else" airlines and international flights. You cannot get from Concourse D to Concourse C without going back through security. I've seen so many people try to find a "secret hallway" that doesn't exist. Save your legs.
Where to Eat (According to the Map)
If you're stuck in Concourse D, I’m sorry. It’s functional, but the food is... fine. The real gems are in the A/B Connector.
- Gachi Sushi: Surprisingly good for airport food. It’s in that middle area between A and B.
- The Sky Azure: This is on the upper level before you hit the gates. It’s got a great view of the tarmac.
- Ledo Pizza: A Maryland staple. If you haven't had square pizza with sweet sauce, are you even in Baltimore?
If you have a Priority Pass, "The Club at BWI" is near Gate D10. It’s usually crowded, but the free snacks beats a $14 soggy wrap any day.
Parking and Ground Transportation Logistics
Parking at BWI is a gamble if you don't check the digital signs on the way in. The Hourly Garage is literally attached to the terminal—great for picking up Grandma, terrible for your wallet at $30 a day.

The map of baltimore washington airport parking lots looks like a sprawl.
- Daily Garage: $16/day. It has a tunnel to the terminal, so you don't have to wait for a bus if you’re a fast walker.
- Long Term Lots A & B: These are the $11/day "budget" options. They’re way out there. The shuttles run every 10-15 minutes, but during peak times, you need to budget an extra 30 minutes just for the bus ride.
For the public transit fans, the MTA Light Rail is at the very end of the terminal near Concourse E. It’s the cheapest way to get to Camden Yards or Penn Station, costing less than two dollars.
Why the A/B Connector Changes Everything
For years, Concourse A and B were separate islands. Now, they’re one massive, fluid space. This 2026 version of the airport map emphasizes the "Connector" because that’s where the best bathrooms and newest charging stations are.
If your phone is at 4% and your flight is at Gate B2, do yourself a favor and walk toward the A/B Food Court. There are built-in USB-C ports in almost all the seating there.
Practical Next Steps for Your Trip
Before you leave for the airport, do these three things:
- Check the Live Wait Times: BWI’s official website actually has a decent live tracker for security lines. Refresh it while you’re in your Uber.
- Download a PDF Map: Cell service in the middle of the terminal (especially near the baggage claims) can be spotty. Have a screenshot of the map of baltimore washington airport ready so you aren't wandering blindly.
- Identify Your Door: If you're getting picked up, tell your driver the specific door number (like "Door 7, Lower Level"). It saves them from circling the loop three times while you hunt for their car.
BWI is a workhorse. It isn't flashy like some of the new terminals in NYC, but it works. Just remember: A, B, and C are friends; D and E are on their own island. Stick to that, and you'll make your flight.
