YYC in WTP earns 90 TP's each way.
CE is 40 TP's each way (except some longer flights earning 80 TP's).
So to qualify for bronze you need 1 longer CE return or 2 regular CE trips.
ahh thank you, it seems i will be stuck at Blue level forever as i doubt i will fly enough to make it into Bronze!
I might try and upgrade to Club one way using avios on YYC-LHR.
Will that earn mean more tier points? despite it being originally booked WTP inbound?
