DALLAS -- Dallas-Fort Worth International Airport has reopened after icy runways forced the major air hub to close for about an hour.
DFW Airport spokesman David Magana says one runway has reopened after the temporary closure Tuesday morning, and crews are working to clear the ice from others.
The airport, the eighth largest in the world, is the main hub for American Airlines. Earlier Tuesday, hundreds of incoming flights were canceled due to the massive winter storm sweeping much of the country.
The freeze has forced the closure of schools and snarled road traffic across much of North Texas. Dallas Area Rapid Transit has suspended rail service because of the storm.
