sorry my english is not that good.
I mean I thought that on top of the 447k miles there were taxes and fees.

Yes I know 1ct per mile is not good, but I have been waiting for a “good” opportunity for a long time. I have a company and run Amex credit cards there and have now accumulated 750k miles.
I would like to go to the Caribbean with my family and the fact that I am now saving about 4k CAD is a good deal for me, as I can do it together with my family and celebrate our 30th birthday there with my wife and children.
