We should get points for both purchases as best I can tell.

I agree there's no way this can work with a third party link or MPX because you aren't using the jetblue/amazon link to amazon.com to make the purchase. In the MPX case, you are just buying an amazon gift card through MPX, so you might actually get other offers but you can't stack the Jetblue offer with MPX.
