Conversely if you're in B or Y booking classes (if you buy latitude ex Canada) you can almost always still get an instant upgrade whether R is available or not.
That's what happens when you taunt AC with a unintended benefit - you loose it.
Very loose :-).
But seriously, the point remains, latitude fares do not necessarily require R inventory for upgrading.
It has been made clear, either in this thread, above, or in another one, that the issue is technical, not policy. And should get resolved eventually.
