RE BOH, CWL, BHX, LPL
LPL- Probably not as the only route they could operate would be to LCY, and VLM has abandoned that market (and MAN) due to the such good rail links the North west now has to London. Liverpool/MAN to London city centre is faster by rail than by air now (centre to centre)
BOH- If a low cost based airline such as RYR cant make BOH work that well for them, what do you expect citiflyer to do?
CWL- again, what market would this be for?
BHX- BA seems more than happy with the codeshare agreement it has in place with BE, so I doubt that it will enter BHX, apart from the few charters it is operating this summer.
