That's something that may work for those arriving/connecting at CDG late in the evening and wanting an early connection out of ATL upon arrival into the US. But do these places want to have scheduled flights taking off and landing at those hours when residents in the area may take additional issue with additional noise/disturbances from flight paths at those hours? And there may beissues with border control staffing, baggage-handling staffing and such at these kind of hours, especially in this era where quality of life issues are part of the picture in employee hiring and retention.
