Dave Noble, that's also what OP is going for, and I understand your point of view. The use of the word "ticket" could mean the whole ticket price. However, it has led to several disputes, and the law is being changed to read "downgraded sector" or whatever the wording is. I'm not 100% sure I'm right, hence my statement about seeing how it will play out.

I also understand the argument of dissuasion that OP puts forward, but I agree with subject2load that I wouldn't seek compensation for something I wasn't denied.
