Just got an e-mail from AA - share miles through 9/30 and get a bonus.
1k-10k 15%
11k-20k 20%
21k-25k 25%
The sharer decides which account gets the bonus.
I'm behind the times, new-ish to AA and didn't even know you could transfer AA miles to a different AA account, lol.
But this seemed cool so wanted to pass it along. Sorry if it's the wrong place.
