fuji,
See my earlier reply: I agree with you, but I don't think it's complex. If you're the only person in the aircraft, you can't claim any money back. If you take one passenger, you can claim 50% back. If you take two, you can claim 67%, etc. The rule is that you must pay your fair share.
However, you and I seem to be in the minority here - everyone else seems to think that it's no problem. Definitely best to get an official answer from the CAA!
