Just more than 74 percent of flights departing this year from Baltimore-Washington International Thurgood Marshall Airport have left on time, compared to over 79 percent in 2009, ranking the region's travel hub 26th out of 29 major airports across the country, according to statistics released this week by the U.S. Department of Transportation.
Both Ronald Reagan Washington National Airport and Dulles International Airport in the Washington, D.C., area outperformed BWI in on-time departures through the first eight months of the year, with 81 percent and 80 percent, respectively. Eighty-nine percent of flights have left on time at the country's best-performing site, the Seattle-Tacoma International Airport, the department said.
