It appears that Amazon will not report the purchase back to HawaiianAir if you merely link through to Amazon and then purchase items that are already in your Amazon basket/cart.
To get the 2-mile-per-dollar credit, you must first empty your Amazon cart (if necessary), link through to Amazon from HawaiianAirMiles shopping portal, and then place items in your basket directly from that link and complete your purchase.
Could be, but as the Amazon Associates program isn't reliant upon that requirement, I would be surprised. In other words, Amazon will still report credit for items placed in the cart before the qualifying session, so I don't see how the airline could be excluding them.
