I noticed just this month that I had extra miles associated and I am not sure why. I purchase my AA tickets and Hertz cars via the card; however, this month I see extra "bonus" miles in which I normally wouldn't see it.

Anyone know why?

E.g. on AA account info website
04/20/10 CITIBANK PLATINUM AA TKT BONUS 0 1,326 1,326
04/20/10 CBAA WORLD ELITE PLAT PURCH 3,494 0 3,494

E.g. on credit card statement
*** AMERICAN AIRLINES AADVANTAGE(R) MILES UPDATE ***
AAdvantage(R) Miles - Accumulated this month: 3,494
AAdvantage(R) Miles - American Airlines travel purchases this month: 1,326

TIA
