Take a look at Airline Routes to see how CX are 'culling" flights to almost everywhere - they made route cancellations/services reductions to flights to 53 destinations on their network yesterday. LGW's dai;y flight is cancelled, MAN reduced from 4 weekly, LHR seems to have full schedule at present, so re-routing MAN & LGW (and any DUB passengers?) from cancelled flights is comparatively easy for them.
