I'm in a pickle here.

As most of you know, I usually travel with my mom. So we're both SE.

She has 13 eUpgrades expiring end of Feb, I have 42 (or 50).

The flights I'd like to upgrade are:
• YYC-YYZ-YYC *2 on M fares = 16. One flight is tmrw in the am and she is cleared from my credits while I'm on the waiting list with J0. That's why my account shows 42 while really I have 50. I could probably enlist the help of the concierge to use my moms eUpgrades. So basically we can downgrade this to 12 eUpgrades. So she would have 1 left on February 29.
• YYC-FRA-YYC *2 on T+ = 56. I should use the ones from my account and 6 from next years'.

Usually I'd do the YYZ upgrades from my account, one TATL from hers and the rest from mine, but AFAIK AC IT only allows one person to use eUpgrades per itinerary.

Am I thinking right?

Thanks for your help!
