Severe weather sweeping across the United States brought major disruption to air travel on Monday, with Logan International Airport among the hardest hit.

By late evening, the Boston hub had recorded 279 cancellations and 339 delays, according to FlightAware. Nationwide, more than 5,400 flights were cancelled as the storm system moved across key travel corridors.

Officials confirmed that the widespread disruption was primarily weather-related, with no major security incidents reported. However, the operational impact was significant, leaving thousands of passengers stranded or scrambling to rearrange their travel plans.

Travellers described long waits, repeated cancellations, and limited communication from airlines.

By midday, all remaining flights from Boston to New York City had been cancelled, highlighting the scale of disruption along one of the busiest air routes in the country.

The latest wave of cancellations underscores how vulnerable air travel remains to extreme weather events, particularly during peak travel periods. For passengers, flexibility – and patience – continue to be essential as airlines work to restore normal operations.
