shortly after the feature was enforced, i booked twice with Expedia an AF ticket
both times, the option never appeared in my Amex account
therefore i called Amex and they told me that the feature didn't concern third party website as part of the agreement between Amex and AF-KLM
in the meantime, this has probably changed ???
