Dallas Weather - U.S. authorities have been forced to cancel thousands of flights at one of the nation's biggest airline hubs because of freezing rain, affecting parts of Texas and Oklahoma.

Reports indicate that for the second day in a row, bad weather conditions have caused major flight disruptions. On Friday authorities canceled 600 flights, and 1,000 flights were canceled on Saturday.

About 5,000 travelers affected by the disruptions spent the night at the Dallas-Fort Worth International Airport. Spokesman David Magana said the airport provided the passengers with blankets, cots and toiletries. He added that they also kept concession stands open overnight.

Fort-Worth based American Airlines canceled about 600 flights, leaving many passengers stranded for hours. According to reports, a flight from Fort-Worth to Oklahoma, which usually takes less than an hour, has become a nine-hour trip.

"We apologize for the frustrating experienced," American spokesman Matt Miller said.

Katie Kacarab, a passenger heading back to California, described the journey as "Extremely frustrating.,"

"We were stuck on the tarmac for three hours. Told we had to get the plane to de-iced," Kacarab told WFAA-TV. "That we were in line, getting ready to do it- it was going to take 20 minutes. We became No.7, plane No. 10."

The National Weather Service has issued a winter weather warning for the Dallas-Fort Worth. This is expected to last until Saturday night. Additionally on Sunday, temperatures are expected to in the upper 40s.

"Main impact...a thin layer of ice on top of prior ice and/or snowfall will continue to make for hazardous travel. Temperatures will be cold enough for additional light accumulations on all roads...bridges...and overpasses. Even in areas where the ice has melted or started to melt...patchy areas of ice are possible on main roadways and on bridges and overpasses," the Dallas winter advisory read.
