A powerful nor'easter (a strong storm that forms along the northeast coast of the United States) is disrupting air travel across the U.S. Northeast. Boston Logan International Airport (BOS) has experienced hundreds of flight cancelations because airlines have had to change their operations due to strong winds and heavy rain.
The most recent confirmed figures from Boston show how serious the disruption is. FlightAware, a flight-tracking service, recorded 253 cancelations and 36 delays at Logan in a report just after 11 a.m. on September 26, 2026.
The storm's impact is continuing into Sunday, September 27. Delta Air Lines said that it expected a large number of cancelations at Boston Logan on Sunday because of the weather. The airline has therefore given affected customers more flexibility to change their travel plans.
Cape Air and Delta Air Lines among the most affected
The cancelation figures from September 26 show that Cape Air and Delta were affected the most at Boston Logan. According to FlightAware data reported by The Boston Globe, Cape Air had 115 canceled flights at Logan on Saturday, while Delta Air Lines had 95.
Cape Air also announced that it had canceled all flights in its North Region because of the weather. The airline said that passengers who were scheduled to travel on affected North Region routes between September 25 and 28 could move their trips to alternative flights until October 2 without paying extra fees.
Regional airports also heavily affected
The disruption has spread beyond Boston. In the September 26 report, 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 serious disruption, and airports in New York and Philadelphia are among those affected by the storm. The exact number of cancelations keeps changing as airlines update their schedules.
Major airlines introduce travel waivers
Several airlines have given passengers extra flexibility because of the storm. Delta's Boston weather waiver covers eligible travel to, from, or through Boston between September 26 and September 29. Under the waiver's conditions, eligible customers can change their travel without paying a change fee.
JetBlue has also issued a Northeast weather waiver, which covers flights operated between September 25 and September 27 involving Boston and several other airports. These include 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 change their flight bookings under each airline's own terms. However, this does not mean that all flights covered by these policies have been canceled.
The situation on September 27 is still developing. Delta has specifically warned customers that a large number of cancelations are expected at Boston Logan on Sunday, while airlines continue to adjust their schedules as weather conditions change.
