according to airlineroute.net, AF is reducing CDG-JFK from 5 to 4 daily when they introduce the ORY-JFK flight. In my view, the dispersion simply makes the route less practical rather than more overall. Flights left:
Outbound: 8.20 (10.25), 14.05 (16.20), 17.00 (19.15), 19.10 (21.20)
Return: 16.20 (05.40), 19.20 (08.35), 21.50 (11.10), and 23.30 (12.40).
