My bad on the OW status. Up early in the US and hadn't had my 1st cup of coffee

But even so, as you state, a Business Class ticket should also be a qualifier. I've saved the OW Lounge Rules page on my mobile so I can pull it up anytime some Lounge Dragon tries to circumvent the rules. Doesn't happen often, but just in case..
