The airport will get a NY service eventually but I hope they're wise in who they chase for one as it has to be a success, the likes of Thomas Cook to JFK would be a mistake. A Norwegian 787 service to a MAJOR NY airport would be a good fit.
Just a question, but why would TCX be a mistake?
They offer a daily service to JFK from MAN, which is probably right and fit for STN to have too at this moment in time, no point going more than daily at this stage. From MAN, They also offer LAX/SFO(not OAK like D8), MIA, BOS and MCO as well as a plethora of Caribbean and rumours of TPA/SAN, which would be a great route portfolio for STN if they could be convinced. I think people overlook just how much TCX can do, and what it currently is doing for MAN, they seems to be pulled in by the Norwegian hype while TCX just get on with it.
Always gets me how enthusiasts of an airport with no service at all to places then become very picky of who should serve the route, surely any service is better than none, it may also stimulate the market?
