Severe winter weather is once again causing major disruption to airports across North America.

More than 1,150 flights were canceled and thousands more were delayed on March 14 as the northeastern United States was battered by heavy snowfall and strong winds.

LaGuardia Airport (LGA) and Boston Logan International Airport (BOS) have both suffered more than 300 departure and arrival flight cancellations.

There were more than 150 cancellations at Newark Liberty International Airport (EWR) as well, and more than 100 at Ronald Reagan Washington National Airport (DCA).

In all, more than 4,700 flights have been delayed, adding to the misery of passengers across the region.

According to data published by FlightAware, Republic Airways was the worst affected airline, with 289 flight cancellations and 251 delays - 26% and 22% of its planned flights, respectively.

The regional carrier uses its fleet of Embraer E170 and E175 aircraft to fly for American Eagle, Delta Connection, and United Express.

Endeavor, which operates exclusively on behalf of parent company Delta Air Lines, was not far behind, with 22% of its flights canceled yesterday, and 24% delayed.

With such a large presence in the affected area, it is not surprising that these two carriers were the hardest hit.

Southwest Airlines canceled 2% of its flights and 21% were delayed.

Due to the sheer scale of the low-cost carrier's operation, these numbers represented 119 and 866 flights, respectively.

Airlines and airports' response
