Hundreds of flights have been grounded in North Texas due to ice and snow that prompted Southwest Airlines to suspend operations at Dallas Love Field.
The National Weather Service on Tuesday issued a winter weather advisory for the Dallas-Fort Worth area.
Southwest spokeswoman Whitney Eichinger said the airline halted all flights at its Dallas hub but hopes to resume operations later Tuesday morning. She had no specific number of flights canceled but says Dallas-based Southwest usually has 125 daily nonstop departures from Love Field.
American Airlines spokeswoman Mary Frances Fagan said the carrier canceled 231 flights Tuesday at Dallas-Fort Worth International Airport. She says American Eagle canceled 90 flights.
DFW airport remains open. Spokesman David Magana said carriers worked to de-ice their planes.
