A powerful nor’easter is disrupting air travel across the U.S. Northeast, with Boston Logan International Airport (BOS) experiencing hundreds of flight cancelations as airlines adjust their operations around strong winds and heavy rain.
The most recent confirmed figures from Boston show the scale of the disruption. FlightAware recorded 253 cancelations and 36 delays at Logan on September 26, 2026.
The storm’s impact is continuing into Sunday, September 27. Delta Air Lines said it expected a significant number of cancelations at Boston Logan on Sunday because of the weather and introduced travel flexibility for affected customers.
Cape Air and Delta Air Lines among the most affected
The September 26 cancelation figures show that the disruption was particularly severe for Cape Air and Delta at Boston Logan. On Saturday, Cape Air had 115 canceled flights at Logan, while Delta Air Lines had 95, according to FlightAware data reported by The Boston Globe.
Cape Air also announced that it had canceled all flights in its North Region because of the weather. The airline said passengers scheduled to travel on affected North Region routes from September 25 through 28 could move their trips to alternative flights through October 2 without additional fees.
Regional airports also heavily affected
The disruption has extended beyond Boston. On September 26 alone, FlightAware recorded 66 cancelations at Nantucket Memorial Airport (ACK) and 44 cancelations at Martha’s Vineyard Airport (MVY). Both airports are important parts of Cape Air’s regional network.
The wider Northeast has also experienced significant disruption, with airports in New York and Philadelphia among those affected by the storm. The exact number of cancelations continues to change as airlines update their schedules.
Major airlines introduce travel waivers
Several airlines have given passengers additional flexibility because of the storm. Delta’s Boston weather waiver covers eligible travel to, from, or through Boston between September 26 and September 29, with eligible customers able to change their travel without a change fee under the waiver’s conditions.
JetBlue has also issued a Northeast weather waiver covering flights operated between September 25 and September 27 involving Boston and several other airports, including John F. Kennedy International Airport (JFK), LaGuardia (LGA), Newark (EWR), Nantucket (ACK), Martha’s Vineyard (MVY), Providence (PVD), Worcester (ORH) and Hyannis (HYA).
American Airlines and United Airlines have also issued waivers for selected Northeast airports and travel dates.
The waivers allow eligible passengers to modify their flight bookings under each airline’s individual terms, but they do not mean that all flights covered by the policies have been canceled.
The September 27 operation is still developing. Delta has specifically warned customers that a significant number of cancelations are expected at Boston Logan on Sunday, while airlines continue to adjust their schedules as weather conditions evolve.
