Sorry to come back again for some clarification from any expert out there....
So it is clear that on 30th July the regular rotation LGW-BFS-LGW-BFS-LGW was interrupted after the first two sectors as easyJet commandeered the aircraft for a late running CPH flight, and did not find one to put onto the BFS service. My view is that this was clearly an operational issue (any arguments there?), but easyJet customer services has not responded to my counter claim for 3 weeks now. Do I go to MCOL or the CAA now? How can I escalate within easyJet (assuming I have a clear case to answer)?
