WHBM - i would be extremly surprised if they are operating a monopoly on the Jer-LHR that they would put an EMB on the route (mind you stranger things have happened) think i read somewhere on PPRUNE that a lot of the LGW pax actually then trf to Heathrow by road to catch connecting flights or are heading to Central London on business.
chrism20 - Yes your right they do, i guess i was more thinking of FlyBE and VGM's smaller props - either way its a big boost to capacity to London and probably very welcomed by Jersey business and residents - think it will do v well.
