I didn't want to hijack the existing TD Aeroplan thread but Mods please feel free to move this is you feel it is appropriate...

In the next while I have to book;
2 tix YVR-YYC-YVR in Latitude for travel in December '21 then;
2 tix in lowest J YVR-MEX-YVR for March '22 travel and;
2 tix in PE or low J YVR-LHR-CDG-YVR for April '22 travel.

I have searched the site until cross eyed to see if there are any overwhelming reasons/benefits to use one ccard over the other for these purchases. During my search I did sign up for the TD Infinite 15x bonus up to a $1000 spend so that was a win but I cannot see anything else current and /or compelling. My spend on the TD card is likely circa $20k this year with little or nothing on the Amex card. As always, any guidance from those more versed on this topic would be most appreciated. Cheers!
