Both Air France and KLM Royal Dutch Airlines offer this option as well as Delta Air Lines. Neither are non-stop either way.
The flights to and from the United States are operated by Delta Air Lines.
If you click through to the final pricing and click the link shown below, you will get marketing carrier flight numbers and fare basis codes. The above DL operated flights will be KL coded due to connections. You don't have to worry about booking non-stop with above dates as the seasonal ATL-ATH non-stop does not return until March 30th.
