I flew a TWA 767-200 in 1988 from JFK to Geneva. The flight was fine, as I recall (except for the 3 hour delay on departure, which at the time was normal for all TWA flights going to Europe and the Middle East from JFK, thanks to TWA's poor route network at the time and its heavy reliance on feed into JFK from a marginal route network, to fill 747's, L1011's, and 767's across the Atlantic.
I would imagine the 762's are dated today and the interiors pretty basic, at best. But, TWA is adding the 763's, which for TWA is a terrific airplane and I bet the airline will use these -300's on some of its remaining European routes from JFK as demand increases. Paris and Milan are well suited for -300 operations by TWA.
