A former TWA employee can correct me if I am wrong. The 727's were not only used for feeding the widebodies, but TWA had several Fifth Freedom routes in Europe. Athens-Rome-Cairo come to mind. I think they also had some sort of agreement with the French that they could actually sell seats from CDG
to a few points in Europe. So it was not only a passenger connecting to a widebody that would fly on a TWA 727 in Europe. An Italian could actually buy a ticket on a TWA flight to Rome or Cairo and not be going to America at all.
In the early to mid 1990's, France changed their rules governing foreign carriers flying from France to other points beyond that foreign carriers country of origin. When this happened, TWA closed the CDG
hub because it couldn't make a profit on 727's providing connection opportunities to JFK
alone. The O & D traffic was gone.
I had a friend who was a Captain on the 727 during this time. He was based at JFK
at the time, but had the opportunity to fly the intra-European 727 routes. I think he had to make a six-week commitment to the operation. His trip paring would be something like a JFK
deadhead. He would then be given a temporary assignment in ATH
and spend his days flying from ATH
to Rome, Tel Aviv, Cairo, and Paris. After six weeks, he went back to JFK
for domestic flying. I think JFK
based Flight Attendants could actually work a 747 trip from JFK
to say Paris. The next day they would fly a 727 trip to Amsterdam, Rome, Athens, or Frankfurt. Then a day or two later would fly a 747, L1011, or 767 back to JFK
. Again, if any TWA folks could elaborate or correct me, please jump in!
