First post here and I am excited to say it is full of good news.

2 x $100 purchased on Platinum - charges posted January 3rd.

Today, AMEX Mobile app shows Airline Fee Reimbursement ($-100 x 2) posted.
This is not reflected on the activity under the website though - only on mobile so far.

"Benefits" section on website shows $200 Airline fee credit redeemed.

Happy traveling!
