Well 6 months on from the original cancelled flight and, through CEDR, I have actually got a ruling in my favour. EasyJet even fought it through CEDR, still saying it was down to ATC restrictions. But in their 'evidence' they shared a document that showed that afternoon they made a last minute switch of aircraft on the LGW-BFS-LGW-BFS-LGW rotation. I guess easyJet's view is that most people will give up, maybe when they say 'no' to the passenger, or then saying 'no' to the CEDR adjudicator in the first round of 'evidence'. Persistence eventually paid off......and that would be my recommendation to anyone caught up in a dubious denial of an EU261 claim
