1) There a lot of misunderstandings about the alleged "Dirty Tricks". BA never admitted gult to any of them, including poaching of passengers and the out of court settlement was over a libel action, not Dirty Tricks per se.
2) There are also a lot of misunderstandings about pricing. Fuel charges are not a rip off or a scam. They are simple pricing decisions which any airline can take at any time. They are shown on the ticket along with something which often is a rip off,- government taxes. Even without " inappropriate conversations" many airlines would change roughly the same anyway for competitive reasons.
So.... no reasons for righteous hysteria about rip offs etc. That would be an entirely separate issue from the legality of conversations. Like it or not, BA is a highly successful business and the fact that it might have been more sucessful if it had not culled most of its older managers and thereby also lost its corporate memory and wisdom is also a different issue.
