I don't think FedEx pilots on intra-Europe will go away anytime soon. More likely is they will be used as bargaining chip by EU next time around to get what EU airlines really want: the right to acquire US carriers. The actual outcome of such a grand bargain actually depends a lot on who runs the US Congress.
I think Air France does flights from KMIA to MTPP and such . Inter carrib in a 320.
Not quite the same. Routing is KMIA-MTPP-TFFF. This is 5th freedom traffic. FedEx intra EU flights is 7th freedom traffic.
