US winter storm: 2,900-plus flights canceled; Austin airport reopens as Delta extends waivers

Travel conditions for Thursday appear dismal as another snowstorm roars across the nation through the end of the week, hitting parts of the country in which millions were already without electricity in record-breaking cold. More than 100m Americans are in the path of the storm as it tracks from the southern Plains to the East Coast over the next few days, the National Weather Service said. But the nation's heartland will get some relief over the weekend, the weather service reported, as the frigid air will begin to moderate over the next couple days. As of 2:30 p.m. EST Thursday, FlightAware counted more than 2,900 canceled flights and more than 1,800 delays. Dallas Fort Worth International still led the world in canceled flights and that airport's dominant carrier, American Airlines, headed up the list of carriers with the most canceled flights. There are approximately 950 cancellations for Friday so far. Austin Bergstrom International Airport reopened Wednesday night, though its south terminal, which serves Frontier Airlines and Allegiant Air, remains closed. The airport said it expects to issue an update about Friday operations by this afternoon.<br/>
