A winter of bad weather in the Midwest, the South and the East Coast disrupted flights all over the country, reducing on-time flight arrivals to less than 68 percent in January, the U.S. Department of Transportation said Tuesday.
That was a drop from 81 percent on time in January 2013, and slightly lower than the on-time rate for December, when the winter weather began to take a toll.
The airlines also said there were 18 tarmac delays of more than three hours on domestic flights and three tarmac delays of more than four hours on international flights. Sixteen of the reported tarmac delays involved Southwest Airlines flights that arrived at Chicago Midway Airport during a snowstorm on Jan. 2. With takeoffs being delayed due to the storm, all the gates at Midway were occupied by other planes.
