Nice find!

I value Air Miles at about 10 cents, so for about $300 in value, and FYF, this is a no-brainer for me.

If your usual browser is like mine, and doesn't allow you to open the links to the T&C, here they are:
https://www.bmo.com/main/personal/cr...te-mastercard/
https://www.bmo.com/pdf/airmiles-world-elite-en.pdf
... and the third link for "AIR MILES Rewards Terms and Conditions" appears to have the wrong URL.

BMO has prevented previous cardholders from getting repeat bonuses.
As a previous BMO Air Miles MC cardholder, I wonder if they'll impose a limit here too.
