I think it's useful to point out that, even though it's all we talk about here, OWE and similar rtw's are uncommon in the "real world", and most of the agents that handle them only incidentally (i.e. the ones you'll find at almost any airport) don't know the rules in much depth.

It's obviously foolish to expose yourself to something that might bite later (swapping order probably being such a toothy one) but it never hurts to ask for a free re-issue.
