What I remember is that TW flew out of JFK to LHR, CDG, FCO, CAI, RID, TLV, SFO, LAX, MIA, FRA, ORD, ATH, MILAN, ZRH, AMS, Istanbul among others. This was during their heyday. TW also flew to BOM via CAI If TW was still around and idiot Icahn didn't sell off LHR for a low price then TW would still fy to all these destinations with the exception of BOM and the Mid east. i'm not sure if they'd fly to FCO considering that so many airlines are pulling out and going for Milan. Istanbul, MAD, LIS, BCN, AMS and ATH would be another question. I do beleive that TW could've made JFK a strong domesticand Carribean base. I don't know if they'd be strong enough to combat AA and CO in South America. Anyone care to take a guess?
TW would still have a strong presenc at LHR and CDG if Ichan didn't sell of LHR and the airline was better runned.
