Why BWI gets delayed
Baltimore/Washington is a thunderstorm airport. Of the 42 FAA programs for BWI in the 12 months to October 2026, 34 were ground stops for storms, nearly all between May and September. When they hit, they stick: the typical BWI ground stop ran almost 3 hours, about double what most hubs see, and summer 2026 brought a 9 h 57 min stop on July 21 and an 8 h 48 min stop three days earlier.
Ground delay programs are rare here, just two all year. BWI's bigger problem is the domino effect of a schedule built on quick turns. Late-arriving aircraft caused 45% of delay minutes in BTS data, more than any other cause, and only 72.9% of departures left on time.
Written by the ATIS Alerts team from FAA Command Center advisories (October 2025 to October 2026), BTS airline on-time data (June 2025 to May 2026) and 20 years of hourly weather observations. Updated October 2026.
