Heavy Rain Grounds Hundreds of Flights at Boston Logan in Hours-Long Ground Delay Program

A persistent band of heavy rain and low clouds settled over eastern Massachusetts on July 30, pushing the FAA to place Boston Logan International Airport into a ground delay program at 11:35 a.m. that stayed in effect until nearly 2 a.m. the next morning. Reduced visibility forced controllers to widen the spacing between aircraft, cutting the number of takeoffs and landings the airport could handle each hour and setting off a chain reaction of delays that rippled across the Northeast.

By the afternoon, the FAA was reporting an average delay of nearly two hours, with some flights held back more than 200 minutes. Twenty-six departures from Logan were canceled outright, about 3% of the day’s schedule, while 144 more, roughly 18%, were delayed. Arrivals fared worse: 235 inbound flights, close to a third of the day’s total, ran late, and 19 were scrubbed entirely.

The disruption capped off a rough stretch of summer weather for East Coast travelers, with storm-driven ground stops already hitting hubs from Chicago to New York in recent weeks. Airlines including JetBlue, which operates a large share of Logan’s schedule, worked to reposition aircraft and crews overnight to limit the damage into Friday’s schedule.

Travelers flying through Logan or connecting through other Northeast airports this week should check flight status before heading out and consider signing up for airline text alerts, since ground delay programs like this one can extend or lift with little notice as weather moves through.
