AD PLACEMENT — CONTEXTUAL
All concourses are connected airside behind security via a continuous corridor with moving walkways, so no shuttle or train is needed. International arrivals (on Concourse E) go through Federal Inspection before re-entering the connected concourse system, meaning international-to-domestic connectors must clear immigration, customs, and a security recheck.

How long do I need for a layover at Baltimore Washington International (BWI)?

We recommend at least 50 minutes for a comfortable connection at Baltimore Washington International. The minimum connection time is 45 minutes for domestic flights and 75 minutes for international flights. Transit between terminals takes up to 20 minutes.

What is the minimum connection time at BWI?

Domestic-to-Domestic: 45 min. Domestic-to-International: 60 min. International-to-Domestic: 75 min. International-to-International: 75 min. These are the shortest layovers airlines will sell at Baltimore Washington International.

Is BWI easy to connect through?

BWI is a single-terminal airport with five connected concourses, making most connections a matter of walking rather than transferring between separate buildings. Southwest Airlines dominates the airport as its largest base, so most connections here are domestic-to-domestic and relatively straightforward, though the walk from one end (Concourse A) to the other (Concourse E) is longer than it looks on the map. All concourses are connected airside behind security via a continuous corridor with moving walkways, so no shuttle or train is needed. International arrivals (on Concourse E) go through Federal Inspection before re-entering the connected concourse system, meaning international-to-domestic connectors must clear immigration, customs, and a security recheck.
