Exactly. These passes are going to fly off the shelf. I've guested in heaps of infrequent flyers over the years and they've almost always been impressed by even the worst Qantas Clubs. It's only through familiarity and comparison that you become indifferent and even jaded to lounges. I have family and friends that always ask me if I have any passes before they fly. While I give them away for free, they have always offered to pay me, and at rates that would make the Qantas bean counters salivate. Qantas is going to make a packet off these lounge passes and going to keep expanding and expanding the sale of them as a result.but when I took both my parents in before a flight, they were both reasonably impressed by the J lounge. And these are the likely candidates for purchase passes, the infrequent once in a while traveller who's also airline agnostic.
The idea that Qantas won't pack as many people as it can into the lounges is laughably naive. I was in the US over Christmas and visited heaps of American lounges. Always packed to the rafters such that you'd have to walk for 15-20 minutes to find a spare set of 2 seats. And in the US, you typically have to pay big money for access even if you're a top tier flyer!! People will walk to the end of the earth and back for a 'free' packet of chips and a beer.
