Hundreds of flights cancelled at Atlanta airport

ATLANTA (AP) For a third straight day, Atlanta's airport was leading all others in the number of cancelled flights.

A total of more than 400 of Thursday's scheduled flights in and out of the airport had been cancelled by 6 a.m. EST Thursday, data from the flight tracking service Flight Aware showed. Many of those flights were cancelled before the day began.

Hartsfield-Jackson Atlanta International Airport is the world's busiest and a major hub for Delta Air Lines.

Delta officials say passengers traveling through Georgia, Alabama, Florida, Louisiana, Mississippi, the Carolinas and Texas may make free one-time changes to their tickets.

Thursday's flight cancellations come after a snow and ice storm struck metro Atlanta around the lunch hour on Tuesday.
