I believe the EXT - MAN service will do very well and attract more "interline" passngers than the Paris CDG service. Many people booking global consolidated air fares through travel agents can only access them in their own country. I believe many more people would book via MAN than CGD (especially travel agents). I personally will not bother with LHR anymore... 4 hours on a coach or an hour in a plane and if you book far enough in advance the prices are very similar! I think WOW may take a hit on some of their PLH - MAN passengers, as this is the only non stop Devon - Manchester route and prices seem to be better with Flybe, but as MV say I think BRS will fill any additional seats left unsold from PLH.
