Let us know if you do reserve to platinum and get the boosts. It would be useful for more anecdotal evidence especially now if people are foregoing choosing the skyclub as a choice benefit.

After moving around through the products, I get the sense that it will be fine and you will get the boosts. Amex’s logic is once you move from one product to the next, you’ve essentially opened a new account (although not actually). So they simply ask: what spend has been achieved and not credited to a boost already.
