tend to agree - almost certainly enough people from the NE going to North America to pay for a daily flight but how many go to New York?
probably less than 50% - the rest go t o Toronto, SFO, LAX and Florida
If someone was staging through and could pick up some passengers it might have worked but these days with a A330 or a B777 almost anywhere in Europe can do a direct flight to the E coast of the USA without a stop
