AD PLACEMENT — CONTEXTUAL
If your connection spans Terminal 1 and Terminal 2, budget extra time for the walkway or shuttle rather than assuming a quick gate-to-gate transfer.
American Airlines connections are almost entirely within Terminal 2, which is the easiest and fastest transfer scenario at DCA.
DCA has no true international arrivals requiring customs (Canadian flights use pre-clearance), so treat all connections as effectively domestic in terms of process, but not in terms of walking distance.
Morning (6-9am) and early evening (4-7pm) are the busiest periods for security lines, so build in buffer time if connecting then.
Gate agents at DCA are used to tight regional jet connections, so check the app for gate changes since Terminal 2's concourses can shift assignments close to departure.

Low risk
Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Terminal 1 (mostly regional and smaller carriers) and Terminal 2 (the American Airlines hub concourses, formerly B/C) are linked by an outdoor/parking-garage walkway that takes about 10-15 minutes on foot, or a free shuttle bus that runs every few minutes and adds waiting time. There is no security re-screening between terminals since both sit landside of their own checkpoints, but you must clear whichever terminal's checkpoint you arrive at if you're coming from outside the secure area.

Can I make a 1 hour 45 min connection at DCA on an international flight?

1 hour 45 min clears the 45-minute international minimum connection time at Ronald Reagan Washington National, but you should still head directly to your gate. Terminal 1 (mostly regional and smaller carriers) and Terminal 2 (the American Airlines hub concourses, formerly B/C) are linked by an outdoor/parking-garage walkway that takes about 10-15 minutes on foot, or a free shuttle bus that runs every few minutes and adds waiting time. There is no security re-screening between terminals since both sit landside of their own checkpoints, but you must clear whichever terminal's checkpoint you arrive at if you're coming from outside the secure area.

How much time do I need for a layover at DCA?

We recommend at least 45 minutes for a comfortable connection at Ronald Reagan Washington National. This gives you enough buffer for security (typically 15 minutes) and transit between terminals (up to 20 minutes).

What happens if I miss my connection at DCA?

If you miss a connection, American Airlines passengers should head to a Terminal 2 customer service desk or use the app to rebook, since AA controls most gates and rebooking options there; other airlines have limited standby capacity given DCA's smaller schedule, so expect possible waits for the next available flight.
