This September and October you can fly from Atlanta to Paris for only $489 round-trip. United Airlines is skirmishing with Delta in the latter’s home town hub.
The outbound routing includes a plane change in Newark, the return includes a plane change in Chicago. The Paris airport is CDG.
Delta may choose to match this fare, since it originates in their major hub airport.
Must purchase 90 days in advance (which means soon), and there seems to be some sort of minimum stay.
