About 37 flights have been canceled at Hartsfield-Jackson International Airport for Tuesday, on top of 148 flight cancellations Monday.
Some flights to the Northeast were canceled due to blizzard conditions in that region.
The airport typically has nearly 2,500 flights a day, including arrivals and departures.
According to airport spokesman Reese McCranie, the airport is "fully operational" with all runways, taxiways and roads open. He added that airlines have not requested de-icing or de-frosting of planes, but de-icing pads are set up to be ready to use if needed.
Airlines are processing passengers as normal, according to McCranie.
Atlanta-based Delta Air Lines is waiving certain change fees for passengers scheduled to fly to, from or through certain cities in the Southeast and the mid-Atlantic region who want to change their flights.
Delta said this morning it had minimal delays, and most of its cancellations were flights coming in from cities such as Washington D.C., Knoxville and Charlotte.
