PITTSBURGH (KDKA) – Airlines have canceled thousands of flights across the country because of recent weather.

In Pittsburgh, dozens of flights were canceled, mostly because of icy conditions at other airports.

Flights to Washington, D.C., New York, Philadelphia, and Chicago were canceled.

One of the airports closed Tuesday morning was the Dallas-Fort Worth International Airport.

On Monday, the Steelers flew into the same airport for Super Bowl XLV.

Today, the airport shut down for more than two hours due to an ice storm.

The airport has since reopened, but subfreezing temperatures are expected in North Texas all week.

As a result, if you’re heading to the Super Bowl, be sure to call the airport ahead of time to make sure your flight did not get canceled.
