About the data

Flights reconstructed from ADS-B, the position signal modern aircraft broadcast to air traffic. Coverage is strongest across North America and Europe, thinner over oceans, polar regions, and parts of Asia and Africa.

The print is a curated selection. To draw the clearest image, I keep the flights with a clean arrival or departure at the airport and set the rest aside; on a busy airport, that can be most of the raw ADS-B. Every stat, route, and total on this page counts only those kept flights.

A few of those kept flights are long-haul, crossing sparsely-covered airspace where the receiver network loses sight of them mid-ocean. That leaves an origin or destination unknown, which I mark rather than guess. They still count in the totals above, but the route-by-route breakdown lists only flights with both endpoints identified.

About Baltimore/Washington International Thurgood Marshall Airport

Baltimore/Washington International Thurgood Marshall Airport opened on July 23, 1950, when Eastern Airlines flew the first scheduled flight, a DC-3, into the airport at 12:01 am. Known then as Friendship International Airport, it had been dedicated by President Harry S. Truman the previous month and was considered the most advanced airport of its era, featuring a 9-story control tower that was the tallest in the country at the time.

The airport occupies roughly 3,596 acres in Anne Arundel County, Maryland, positioned almost exactly between Baltimore and Washington, D.C. That geography is its defining advantage. It serves both metropolitan areas simultaneously and is the busiest of the 3 major airports in the region. In 1973 the name changed to Baltimore/Washington International Airport to signal that dual mandate more clearly, and Maryland had purchased the facility from the City of Baltimore the previous year for $36 million. A $70 million terminal expansion completed in 1979 doubled passenger capacity. Then, in October 1980, the BWI Rail Station opened, the first intercity rail station built on airport property in the United States, connecting the airport to Amtrak's Northeast Corridor and MARC commuter rail. On October 1, 2005, the airport was renamed again to honor Thurgood Marshall, the Baltimore-born civil rights attorney who became the first African American justice on the U.S. Supreme Court.

Southwest Airlines arrived in September 1993 and transformed the airport's character. Today Southwest accounts for more than 70 percent of passenger traffic, operating as a focus city out of Concourses A and B. The airport operates a single terminal with 5 concourses and 73 gates. International service, including British Airways, Icelandair, and Copa Airlines, departs from Concourse E. BWI handled more than 27 million passengers in fiscal year 2024, its busiest fiscal year on record.
