ATLANTA – Delta Airlines officials say more than 500 flights in Atlanta have been cancelled because of a winter storm that’s approaching the region.

Delta spokesman Morgan Durrant said Monday night that 313 mainline flights and 196 Delta connection flights at the Hartsfield-Jackson Atlanta International Airport have already been cancelled for Tuesday.

Durrant says the airline will revise the number Tuesday afternoon and will give updated cancellation numbers for Wednesday.

Delta is offering customers expecting to travel through several Southeastern cities between Tuesday and Thursday the opportunity to make free one-time changes to their itineraries, whether or not their flights have been cancelled.

The waiver applies to travellers passing through Atlanta, North and South Carolina, Huntsville, Ala. and Norfolk, Va.
