2 operators run this water, from 20 min to 24 min — a difference of 4 min on the same crossing. Washington Union Station has an airport 6 km from the quay, so this is a crossing you can make one way and fly the other.
One row per operator and speed. Where a service is sold as fast and its average does not clear 45 km/h, the word appears in quotation marks — the boat is fast craft, the crossing is not.
If this crossing does not suit, these quays also reach Washington Union Station without a change. It is the question a single-route page cannot answer about itself and an atlas can.

Our records for the Bwi Thurgood Marshall Airport Station–Washington Union Station crossing were read on 11 August 2026 and describe the network as it ran that week. We hold no month-by-month variation, so this page cannot tell you whether a crossing runs in February.
If you are travelling well outside August 2026, confirm with the operator before you plan around it.
No fares. The choice between Amtrak at 20 min and MARC at 24 min is mostly a price decision, and we hold no prices for either.
No departure times. No rate is held for this pair either, so we cannot say how often it runs.
