They've really painted themselves into a corner here. To me, their problem now is everyone "earned" their access through engaging with AS and their programs. I may not fly enough to earn status and day passes, or to warrant Lounge membership, but I did pay for the Summit card with the reasonable expectation that I'd be able to use the passes when I do travel. This wait list when the lounge isn't really full worked ok when they were turning away Priority Pass members, those folks didn't engage with AS to earn entrance and may not even have been flying AS.
