Well that was unexpected - it worked:
As a benefit of your American Express Propel World℠ Credit Card, you receive up to $100 in reimbursements for qualifying incidental airline charges per year.
You've earned an airline reimbursement based on your recent airline transaction(s):
Credit Amount $25.00
I also logged into my account and it shows that the $25 MPX purchase and the $25 airline credit have both posted.
