More than 3,000 flights canceled as latest winter storms sock US

More than 3,000 flights to, from and within the United States were canceled on Thursday and Friday as a sprawling winter storm system brought rain, snow and ice to states as widespread as Texas and Massachusetts.

On Thursday, 2,147 U.S. flights were canceled, according to FlightAware, more than half of which were scheduled to fly to or from the Dallas-Fort Worth area, which saw cold temperatures and freezing rain.

In total, 1,142 flights to or from Dallas Fort Worth International Airport (DFW) were canceled, which accounts for roughly 57% of the airport's daily operations. Another 201 flights at Dallas Love Field (DAL) were canceled.

American Airlines led the cancellation count with 686 mainline flights, nearly a quarter of its schedule for the day, followed by Southwest with 370 flights (10% of its schedule). Both airlines are headquartered in Dallas. Many of the cancellations were made proactively in preparation for the storm.

The situation in Dallas was largely resolved by Friday morning, with just a few dozen cancellations and delays. But as the storm system moved into the Northeast, the precipitation, rain, sleet and snow led to another 1,417 delays as of 11 a.m. ET.

Air travel has been heavily affected by storms this winter, with continuous bad weather compounding operational difficulties during the holiday period linked to the spread of the omicron variant.

The good news for passengers is that airlines have begun to cancel higher numbers of flights proactively once weather forecasts firm up, instead of waiting for the day of the storm.

That means that instead of watching delays stack up before flights are eventually canceled, passengers can find out as much as a day or two ahead of time, allowing them to manage their schedules before heading to the airport.

If you find yourself facing a cancellation or severe delay, here are TPG's tips for managing those flight delays and cancellations.
