Using BWI on air freight documents
The three-letter IATA code BWI is what goes on an air waybill, a booking and a flight schedule for Baltimore/Washington International Thurgood Marshall Airport; the four-letter ICAO code KBWI identifies the same airport in flight plans and air-traffic control and does not appear on cargo paperwork. A forwarder quotes airport-to-airport between two IATA codes unless the booking is door-to-door, so the code fixes where the rate applies.
For a US import, Baltimore/Washington International Thurgood Marshall Airport is also a customs port of entry. The Census Schedule D list names it as port 1305, and that four-digit code β not BWI β goes in the port field of CBP Form 7501. Airlift coordinates entry filing through our licensed broker network.
