A while back there was an AC promo that allowed you to overnight in a hotel ( for free ) when travelling business class. For instance if I was doing YVR -- YYZ -- LHR, I could choose to stay in YYZ and then fly out the next day to LHR.
I did try using the search option but no matter what I plugged into the box nothing seemed to bring up this promo
Hoping somebody on here knows which promo I am referring to and if it is still available. Thank you
