I will be travelling with a friend who has no oneworld status. We will be flying BA lhr-yul. Can she line up with me in business check-in counter or will the counter agent crack up and say 'back, back, back to the other line. (slight exageration). I can access business due to silver and qc m'ship.
I am thinking if I get through quicker and have to wait and wait for her to get checked in through economy check-in, will be a bit annoying.
