500 mile upgrade question
I used to fly AA a lot but no longer have status. I have 20 in my “500 mile upgrade balance” and after several rounds of drudging through their site and the “sticker” thread here and still am not clear whether/how they’re useful on an upcoming flight. I’ve booked two AA AAnytime reward flights from MCI-CUN. Can I use these upgrades and if so what will it achieve/how do I do it?
