It has been a whole statement cycle since the announcements were made regarding 5x MR points for booking direct flights. Some of your crafty people thought, why not try to get MPX to code for flights and get 5x? Guess what the RAT has it figured out and you only get the 1 point for $1 spent, and forget about MPX working for the $200 fee reimbursement.
So there you have it, the $200 travel credit still works on the Gift Registry still. Better yet, we still got the 5x points on a United Ticket paid mostly with the gift registry with the remaining balance paid on the Platinum.
