- Minors (as defined by the laws of the territory where the lounge is located) must be accompanied by an adult when visiting a Maple Leaf™ Lounge.
Also lists the airports with Maple Leaf lounges. They include Calgary (domestic). My flight to LHR is obviously int'l, so not sure whether I'd be able to access the domestic portion of the terminal, or whether there's some sort of substitute lounge at the international terminal.
You would arrive in one of the domestic piers in Calgary (and need to walk by the domestic lounge to get to the international terminal. So you should be able to get in there.
There is no security screening (just a boarding pass check going from domestic to international). Some accommodation has been made to use the pay lounge in the international area for premium cabin passengers, not certain if that applies to this pass product.
