ANA lounge is a departure lounge, she won't have access without a departing boarding pass in J, status, or lounge membership. (It is part of priority pass)
Damn ANA lounge is now Priority Pass?
With UC and Maple Leaf membership, you only get to guest 1 person into ANA lounge and you have to be flying Star. If I’m not mistaken, PP lets you guest 2 and you can be flying any airline.
It was already a fairly crowded lounge (at least before pandemic). With day pass and now Priority Pass, it’ll be a zoo unless they leave PP as soon as the pandemic is over.
