I'll assume the ancillary revenue part is the main reason AC signed with AIMS....and maybe the system will help ensure AC gets paid for those other *A pax who stumble into an MLL.
"The company making the software helps airlines sell memberships and lounge access, as well as generate ancillary revenue from the lounge. They system helps airlines bill partners for access. They’re in 89 lounges at this point."
And today, Gary Leff offered tips. (Does anyone know if AC reads his site?

)
"It seems to me that if you’re going to buy a refundable ticket just for the lounge access, you should:
1. Not use that airline’s frequent flyer number (or any frequent flyer number) associated with the ticket. For a one-off that’s probably sufficient. But if you’re the type of person looking to eat free for a year in a lounge you probably don’t want to use a credit card associated with your mileage account. You may even want a separate boarding pass to clear security from the one you use to enter the lounge so that even more information can vary from what’s in the airline’s records about you.
2. Not refund the ticket until you leave the lounge.
3. Not use the same lounge over and over on tickets you’re cancelling day after day.

Despite the access to alcohol, I am not sure that people are clamouring to get into AC's Dom & TB MLLs for the pickle buffet.
