More than 2,800 flights within, to or from the United States have already been canceled as of 10 p.m. ET on Sunday, according to flight tracking website FlightAware. And the delays of flights still able to take off were around 6,700. Christmas Day is traditionally a light day for passenger flights.
Demonstrating the scale and widespread effects of the storm, it was an airport in the Deep South and another in the West that were the most affected on Christmas Day. Hartsfield-Jackson Atlanta International (ATL) — the world’s busiest airport for passengers — had the second-highest number of cancellations and delays at 10 p.m. Sunday.
The No. 1 was over 1,000 miles into the Rockies with Denver International. And even further west, Harry Reid International (LAS) in Las Vegas had the third highest number of cancellations.
The effects of the storm in parts of the West are easing, however. The temperature at 8 p.m. MT at Denver International was still above freezing at 38°F (3°C).
In hard-hit Western New York, things were still too tough for humor.
The temperature at BUF at 10 p.m. ET was 20°F (-7°C) with winds of 24 mph, according to the National Weather Service.
A difficult week to fly

The arrival of the massive storm was untimely for travelers who had begun to push the number of Christmas week flights back to pre-pandemic levels.
On Christmas Eve, there were a total of 3,487 canceled flights, according to FlightAware. Friday was the worst day with 5,934 cancellations, while Thursday saw nearly 2,700 cancellations.
This winter weather megablast in the eastern two-thirds of the country is expected to slowly moderate over the last week of the year. As of 5:30 p.m. ET, there were still more than 260 preemptive cancellations for Monday.
