TCX
From what I saw/heard,
TCX A330's will operate 3 weekly JFK and 2 weekly MIA
BOS I haven't heard of as yet
not a clue as to why they are doing it or even who for because it doesn't fit in with their "charter" profile at all
and strange that they haven't announced it in an all singing/all dancing way rather than let it drip out in the news slowly
