U.S. airlines are preparing to gradually restore flight schedules on Tuesday as they recover from widespread disruption caused by a powerful winter storm that crippled travel across the Northeast and led to more than 8,000 flight cancellations and delays.
The storm dumped heavy snowfall across large parts of the northeastern United States, shutting down roads, forcing school closures and prompting authorities in several states to restrict non-essential travel.
By Monday evening, thousands of stranded passengers were still facing cancellations. Carriers including United Airlines said they were planning to increase operations on Tuesday, while warning that weather conditions and airport recovery efforts could continue to pose challenges.
Data from aviation analytics firm Cirium showed that around 7% of U.S. flights were expected to be canceled on Tuesday, a significant improvement from more than 19% on Monday. Under normal conditions, daily cancellations typically hover near 1%.
Southwest Airlines said it was on course to begin ramping up services, provided conditions allowed for safe operations. The Dallas-based carrier canceled roughly 7% of its flights on Monday, fewer than many competitors due to its relatively limited exposure in the Northeast.
American Airlines confirmed that it had resumed flights at Ronald Reagan Washington National Airport and Philadelphia International Airport.
Both American and Delta Air Lines said they expected to restart operations later Tuesday morning at LaGuardia Airport, John F. Kennedy International Airport and Boston. Delta also anticipated resuming flights at Newark.
JetBlue Airways suffered the most severe impact, canceling nearly 80% of its flights on Monday, according to FlightAware. The airline said total cancellations linked to the storm will reach about 1,600 flights through Wednesday.
Travel disruption extended beyond air travel, with Amtrak canceling dozens of train services between New York and Boston, as well as on other Northeast routes.
Overall, American, Delta and United each canceled roughly 20% of their flights on Monday. The storm delivered more than 2.5 feet (76 cm) of snow in some areas, making it one of the heaviest winter events of the season.
