Then perhaps AS should not have joined OneWorld? But they did and nobody forced them to. And since they did, they should be required to abide by the same OW policies and procedures that every single other partner adheres to when providing OneWorld specific benefits, which in the context of this discussion, lounge access is one of them.

OneWorld requirements for accessing lounges are very clear regarding what is required to gain entry. AS should not be allowed to just make up additional rules because they don't want to provide the benefit as documented/stipulated. If they want the OW guidelines/policies to be different than they currently are then they should lobby the alliance to modify the language and update the requirement for all.

As others have stated, AS isn't a "special case" just because they want to be (or because you seem to want them to be).

It's seems that AS wants the benefits of being aligned with an major alliance, but somehow believes they should get to be a "special snowflake" when honoring the benefits that cost money. And yes, lounge access costs money for all the carriers to provide, but that is part of being in an alliance, which again, nobody held a gun to AS's head to join...

Making pithy little comments like, "That's it's" doesn't, ipso facto, make it OneWorld policy just because you wish it be. By all means, please point to any OW documentation that clearly states that having the FFP # of your status in the reservation is required for lounge access. Of course you won't, because you can't. If the OW guidelines can't be trusted to be accurate, why even have them? Just say each airline can make up whatever requirements they'd like, based on their individual business model, when you show up at the lounge entry desk...
