Eupgrade question
 

So i was waitlisted on my flit from lhr-yyz for an upgrade but I was successful at the gate. In the YYZ MLL I proceeded to upgraded the second segment, YYz to ORD. I believe I will not be charged 6 credits for the second segment since its one PNR and the first segment was more costly. Am I correct because the lounge dragon says otherwise?

If the YYZ-ORD flight takes place within 24h after arriving at YYZ from LHR, you won´t be charged any additional upgrade credits.

The number of upgrade credits is based on the distance from origin to destination. As both LHR-YYZ and LHR-ORD are <5000miles, you´d be charged 14 credits when upgrading from T+.

That was te case in the old days of SWU's and SSWU's. I thought the connection on an international flight now has to be within 6 hours to be included in your international upgrade, but can't seem to find it on the AC site.

I´m pretty sure it´s max. 24h for connections to/from int´l flights, but max. 6h for connections within Canada/US (even when it´s part of an int´l itinerary).

E.g. FRA-YYZ(max. 24h)-YVR(max.6h)-YEG

I ended up getting charged 14 for LHR-YYZ and 6 for YYZ-ORD. How long does it take to get refunded or should I be on the phone to Aeroplan right now?

IMHO you shouldn't bother phoning in. I've had great (and speedy) responses using the following form on aircanada.com.

Thanks. I submitted the form but it unfortunately says it may take 10 business days. My return journey is on May 18th and I am now short 3 credits to process the upgrade. Really hope they can sort this quickly!
