It did not work for me either in December!! I presume MPX is dead for Amex!!
As will their PRG be for me before AF because MPX is dead; Have the Ritz/CSR for travel credits that are ALOT more flexible. I will keep the ED to bank my MR's until I use them. Sitting on approx 180k MR's, how to best use them for a flight/flights is my goal sometime this year.
For people sticking with United, at least the gift registry still works.
I did a mix of bags and MPX for 2016 (I was mostly flying AA with Platinum Select) but am going with Delta for 2017 (bags, lounge guest fees, and maybe a $50 gift card).
Yes, I used the United gift registry method twice in December without a hitch.
Any luck, UncleB?
I'm sorry to report nothing yet... I'm fairly certain it's dead, but in another few days I'll be willing to call it for certain.
It doesn't sound like many of us use the full credit through natural spend...
