Thanks for all the advice guys. We have withdrawn the request for the Easyjet fare refund and have received an email from BA confirming this.
Concerning the BA offer they state "I am sorry to hear that you do not want to accept the cheque and voucher we offered you. We realised that we had let you down and wanted to pass our apologies to you, together with a gesture of goodwill"
That's a new definition of goodwill in my book!
We'll stick to a full refund of all costs plus 400 Euros for "denied boarding" on the basis of breach of contract resulting from twofold errors by BA (getting the "no show" wrong in Glasgow and then refusal by BA representatives in Gibraltar to verify the facts of the case before denying boarding.
We will continue to make an infernal nuisance of ourselves (letters to CEO, CAA, press etc) and will use small claims court if it goes that far.
cheers again guys
