TULSA, Oklahoma - Freezing rain that coated parts of Texas and Oklahoma for the second consecutive day left highways slick and forced the cancellation of another 1,000 flights Saturday at Dallas-Fort Worth International Airport, one of the nation's biggest airline hubs.

The Saturday chaos was on top of about 600 flights nixed Friday, forcing about 5,000 travelers to spend the night at the airport, spokesman David Magana said.

The airport provided cots, blankets and toiletries to the passengers, plus kept concession stands open overnight, Magana said.

The Tulsa International Airport is reporting cancelled flights to Dallas-Fort Worth on its website.
