Whilst I agree that I we shouldn't expect a free upgrade, the issue is more of a possible mislead. For ever and every Q, on any flight, from anywhere to anywhere, as always been upgradeable. Now, for this one off, the rules is changed. What happens when it happens again on another route and then another and another. Eventually Q will become another W/V, perhaps the cheap Biz classes too.

Maybe I'm exaggerating a little, but you get the idea. I just think its a bit of a mislead.
