yes easyjet but you need a min demand in order to make a service viable for them based on the capacity they offer, I'm pretty sure they don't view the CI as a target ripe for picking, I'm sure they have the whole of flybe / eastern route data to chew through first prior to taking any risk and the GCI/LGW route and thats even even after a r/w extn that everyone harps on about is more of an ATR route than 150+ seat route.
now if ezy ever bought a fleet of E190E2's then yes - they would put both flybe / Eastern and Aurigny out of business...
