Snow and ice are causing flight delays and some cancellations at Hartsfield-Jackson International Airport on Wednesday.
More than 700 flights have been canceled Wednesday at the Atlanta airport by Delta, Southwest and other airlines, according to data on FlightAware.com. The Atlanta airport typically handles close to 2,500 flights a day.
Hartsfield-Jackson, the world's busiest airport, got more than 1.5 inches of snow, and some of the airport's runways were closed early Wednesday morning, according to Delta Air Lines.
Delta canceled about 900 flights across its system Tuesday and Wednesday.
Temperatures are expected to remain below freezing all day Wednesday. Delta brought in deicing workers from its Minneapolis hub to help deice planes at the Atlanta airport. Deicing can require more time and cause delays.
"Operations are resuming, though at a slowed pace," Delta said.
Flights arriving in Atlanta were being delayed an average of more than two hours due to snow and ice Wednesday, according to the Federal Aviation Administration.
A ground stop also affected flights Wednesday afternoon.
Passengers should check their flight status and sign up for notifications if possible. The airline is waiving certain change fees for passengers scheduled to fly to, from or through dozens of airports in the Southeast and in the Northeast who want to change their travel plans to avoid potential weather impact.
Southwest Airlines has also warned travelers that flights could be affected by weather in Atlanta, Birmingham, Houston, New Orleans, Raleigh-Durham and Richmond, along with airports in the Northeast, and is allowing passengers to change their travel plans without paying an additional charge.
Snow falling in the Northeast on Wednesday is expected to affect flights there, and Delta has already canceled flights in New York and Boston, but said it "does not expect a significant disruption at those or other Northeastern airports.
