I assume this is a fare mapping issue or something similar, but I can't actually figure out what's going on. I hope it's okay for me to post it here.
Google Flights is showing a price of $3,128 for JFK-CDG-DXB in F on select dates from September onward (
example), on Delta-marketed Air France flights. However, there is no direct booking link, and it doesn't seem to show up on OTAs. Maybe someone more knowledgeable can make something of it?
