They're putting together quite a long haul portfolio from LGW in fairness, quite a few Far East destinations in the pipeline.
SIN loads are reportedly dire, I wouldn't bet the bank on this working out. Huge expansion West followed by big push East, whilst drawing down profitable short haul to bet on higher yielding long haul. That's a LOT of balls not to drop. Norwegian wouldn't pick up UK domestic at the same time as all of that would they?
