:unsure: Sorry! But I think TWA sold those slots to Olympia years ago. 🙄 Flow there on our Honeymoon, along with, Lisbon, Madrid, Rome, Athens, Frankfurt, Londen, back to the good ol U.S.A.!!! All on good ol TWA!!! At the time, TWA, and Pan Am, were the only two US carriers who could do that!!!We had a small fleet of 727's that just flow from point to point in Europe!
