Are Terminal 1 and Terminal 2 connected at DCA?

Yes and no. Terminal 1 and Terminal 2 at Reagan National Airport (DCA) are connected before security by an indoor walkway and a free shuttle bus. After security, they are completely separate. Moving between them mid-layover means exiting the secure area and clearing a second TSA checkpoint.

Yes and no. Terminal 1 and Terminal 2 at Reagan National Airport (DCA) connect before security via an indoor walkway and a free shuttle bus. After security, they are completely separate buildings. Switching terminals mid-layover means exiting the secure zone and clearing a second TSA checkpoint, so check your gate before you go anywhere.

The short version on DCA's two terminals

Reagan National has two main terminals: Terminal 1, covering gates A1 to A9, and Terminal 2, covering gates B10 to E59. The airport opened in 1941 as Washington National Airport, and part of that original building is still in use as Terminal 1. Terminal 2 opened in 1997.

The key thing to understand: the connection between them depends entirely on where you are in the airport.

Before security: yes, they connect

The two terminals are separate after security but connected before it by an indoor walkway and the airport shuttle bus. A landside walkway connects the two terminals near the conference rooms in Terminal 1. That path runs through the parking and check-in zone, so it stays open to anyone, ticketed or not.

You can walk the indoor walkway on the landside or take the free airport shuttle bus, which runs 24 hours a day between the terminals and the parking garages. A terminal shuttle stops on level 3 of National Hall and outside Terminal 1 and runs every 15 minutes on average. Alternatively, you can walk between the two terminals, with the farthest distance being a roughly 10-minute walk.

After security: a hard stop

This is where travelers get tripped up. Post-security, the terminals are not connected. You must exit, walk across, and re-clear security.

Connections to carriers in Terminal 1 (Frontier, Air Canada, Southwest) require exiting security. The entire National Hall, running north to south and connecting Concourses B through E, is fully airside, so moving between piers within Terminal 2 does not require a security re-screen. That convenience applies only inside Terminal 2.

Which airlines are where

Southwest, Frontier, and Air Canada use Terminal 1. American, Alaska, Delta, JetBlue, and United use Terminal 2. The four Terminal 2 concourses are connected by National Hall.

If you booked a connecting itinerary that crosses terminals, leave extra time. Terminal 1 and Terminal 2 are physically separate buildings, requiring a walk or shuttle ride that eats into short layovers.

The terminal names changed recently

Some older tickets and signs still use the former letter designations. The former Terminal A became Terminal 1. The former Concourse B/C was renamed Terminal 2 and contains Concourses B, C, D, and E. The re-naming followed completion of Project Journey, a $1 billion capital project that built two new security screening areas and added a new concourse to accommodate American Airlines' regional flights, which formerly required a bus ride to remotely parked planes.

Getting to DCA by Metro

The Reagan National Airport Metrorail station, on the Blue and Yellow lines, is an elevated station next to Terminal 2, linked to its concourse level by two enclosed pedestrian bridges. From Terminal 1, take the indoor walkway or the airport shuttle bus to reach the Metro station.
