On Monday 14 September 2026, Boston Logan International Airport (BOS) ranked among the day’s hardest-hit U.S. gateways. FAA NAS Status showed a Ground Delay Program (GDP) citing runway construction, while flight-tracking summaries (FlightAware-style tallies relayed by travel press) put Logan near the top of the national disruption list.
Why Logan is constrained
Massport has been running a planned multi-week closure of Runway 9/27 for an EMAS safety upgrade — work expected to keep cutting operational flexibility through mid-November, especially in afternoon and evening banks. With one runway offline, the FAA meters arrivals with a GDP rather than letting volume overwhelm the remaining configuration.
Public FAA-style program snapshots for 14 September listed average delays on the order of roughly one hour (figures moved through the day; some trackers cited peaks above 100 minutes). Treat those averages as directional and always reconfirm on your airline app.
Passenger impact — and the New York backdrop
Press tallies for the day pointed to hundreds of Logan delays plus dozens of cancellations, with JetBlue especially exposed as Logan’s largest carrier. The same national wave also showed heavy delay counts at JFK and LaGuardia — separate from the Sunday 13 September thunderstorm ground stops already covered — as Northeast weather and volume kept New York metering sensitive.
Recheck status before leaving for BOS; build buffer on Boston–New York shuttles and same-day connections. If the schedule cannot slip, a private jet or empty leg can bypass airline recovery banks. Rahizi qualifies the brief and returns partner options.
