BATCAT is not applicable, if one goes to an overseas destination not served by AC - eg trying to go to Lisbon from Ottawa, I am flying from YOW to LHR on AC, and from there to LIS on TAP. Although I am flying on a revenue business class ticket, BATCAT does not apply unless the whole route is flown on AC.
Conversely, if I wanted to fly from YOW to LHR on an economy ticket (and then upgrade), BATCAT does not apply. I can use instant KK for the companion to get an economy class award ticket - however, the companion can not upgrade.
