Here's the detail from Amex:
"baggage fees, flight-change fees, in-flight food and beverage purchases, airport lounge day-passes, pet-kennel fees, and phone reservation fees"
The problem is that you have to choose one airline for this and the selection lasts a year. Here's the list of airlines that qualify:
AirTran (merging with Southwest)
So it looks like that will work for you. More details here on this blog post: http://travelsort.com/blog/maximizing-the-amex-platinum-airline-fee-credit
As for the international ticket program, I would seriously doubt they'd allow you to use airline miles for that. It's cash or MR points only and I don't even see the program details mentioning MR points.
