It was all going so well, then you throw these two routes into the mix!
These are the two routes what every UK airport has at the top of their dream list if they don't already have them!
Unless you can demonstrate a source, both are very unlikely...
United are committed to Heathrow, and would IF they really did want to fly from another London airport. fly from the likes of Stansted or Gatwick, where the old Continental (before merger with United) flew from both.
Continental made Gatwick to Newark work for years, and flew the route profitably with 3-4 flights a day. They only moved to Heathrow, because of the open skies agreement with the USA and routes like this are even more profitable from Heathrow and was better to just have one London base than two on a cost basis.
Gatwick is publicly screaming out for a scheduled NYC route, and would flight tooth and nail to obtain the route from other London airports, and that probably even goes as far to offering some sort of subsidy to fly the route.
The likes of Emirates have 40+ Premium seats on their aircraft, Luton does not have a lounge cable of handling this number.
