As others have stated, there are a set of standard OWR benefits that all OW airlines have to provide to all OWRs. Then, individual airline’s may give their own OWR elite equivalents extra benefits. AA, for example, gives their OWR the additional benefit of being eligible for space available free upgrades on every domestic and short haul intl flight, but don’t expand that benefit to other OWRs. Just as QR give’s their OWR the addiontal benefit of priority boarding.
