Hi all!
I'm a relatively frequent flyer on AC. My dad has 50K and we are heading to LHR next month from YYC. I'm booked in Premium Economy (lowest) and my dad has a flex fare. He would like to use his upgrade credits to upgrade us on the flight. ExpertFlyer is showing ten J seats still available. Does he go ahead and just request the upgrade on the eUpgrade site, or do we have to wait until a certain time since he isn't E or SE? And we are traveling on different bookings. I believe I read that even though I am on a different booking he can still request an upgrade for me which his credits, is this the case? Sorry neither of us have upgraded before so any advice is appreciated. Thanks!
