Thanks for the detailed explanation on the lounge situation, WR Cage. I'd been told there was no new transborder lounge, but good to have the additional context on the overall setup in the new terminal.

Unfortunate that there isn't a MLL given that YYC transborder pax volumes are >3M passengers per year. That being said, AC doesn't operate a lot of transborder flights on their own metal (plenty of UA codeshares), so I can understand some of the reasoning.
