eggc- Anything from Norwegian will be interesting seeing as they have started their long haul operation at Gatwick this week. I don't think an LAX route will be viable nor anything really apart from something aimed at the leisure market but obviously Florida could be an option.
I would of thought there would be plenty of room for flight-only competition in that sector where Virgin and the package outfits are dominant. To me the offerings from Monarch/TCX could be blown apart by a superior Norwegian 788 straight into MCO.
