Disruption overview
Boston travelers faced a difficult evening on 21 July 2026 as severe thunderstorms hit Logan International Airport (BOS), pushing cancellations past 300 and delays beyond 400. Republic Airways and JetBlue Airways were hit hardest while heavy rain, lightning, and strong winds created wider congestion across the Northeast. Because the disruption was caused by weather outside the airline's control, compensation is usually unlikely, but airlines should still offer rebooking or refunds, along with care and assistance during longer delays. If you want to understand what may apply in your case, AirHelp's free flight checker is a simple place to start.
Disruption details
Powerful thunderstorms caused major disruption at Logan International Airport in Boston on Tuesday, 21 July 2026, with more than 300 flights canceled and more than 400 delayed by late that night. Heavy rain, lightning, and strong winds kept arrivals and departures moving slowly as the storm system swept across the Northeast.
For passengers, this meant long waits, last-minute schedule changes, and difficult rebooking decisions across both departing and arriving flights. The totals kept rising through the evening as new storm cells moved through the area, making it a tough day for anyone traveling through Boston.
The heaviest disruption fell on two airlines:
Republic Airways recorded 114 cancellations and 55 delays.
JetBlue Airways recorded 73 cancellations and 109 delays.
Other carriers also saw scattered disruption, but none were affected on the same scale as Republic Airways and JetBlue Airways.
At Logan, the worst of the weather developed during the afternoon commute and intensified into the night, leading to temporary ground stops at intervals. Successive rounds of heavy rain, lightning, and gusty winds made it harder to keep planes arriving, departing, and turning around on time, which is why delays escalated quickly into cancellations for many travelers.
Logan International Airport handles around 40 million passengers a year, so disruption on this scale can spread quickly through airline schedules. This was the biggest single-day weather disruption at the airport so far in the 2026 summer season.
Because these delays and cancellations were caused by severe weather outside the airline's control, compensation is usually unlikely under rules such as EC 261. That doesn't mean you're without support.
If your flight was canceled, your airline should offer a rerouting option or a refund. If you were left waiting for hours, it should also provide care and assistance such as food, refreshments, or accommodation when needed.
If you're traveling through Logan, it's worth checking your airline's latest updates and the FAA's real-time airport status information before you leave for the airport. And if you want to understand whether compensation could still apply in your case, AirHelp's free flight checker is a simple place to start.

Care and assistance
Your airline must provide food and refreshments if your journey is delayed more than a few hours.
Accommodation
If you are away from home and your journey is delayed overnight, the airline must offer you accommodation and transportation to it.
Communication
Under EC 261 you are entitled to 2 phone calls or emails if your journey is delayed over 1 hour. No compensation when a disruption is caused by extraordinary circumstances, as this appears to be.
