I am booking a flight TLV to JFK.
Which is the easiest airport to transfer planes with a short stopover time paris or rome?
If I go airfrance and then transfer to a delta flight does that make the change any more difficult? Different terminal?
Will I need to go through security?
thankd
Air France and delta are the same at CDG. You might have to transfer "terminal" (it's actually not a different terminal as all SkyTeam ultra schengen leave from terminal 2E but 2E is divided to 3 parts, gates K, L and M), there's a train every few minutes that go from one to the other. I don't think that you're able to know in advance which gate you'll arrive/depart.
Overall I think that connecting internationally at CDG is very smooth.
