Quote from AA:
"In the second half of 2016, award miles earned from flying will be calculated differently to reward you when you spend more. When traveling on flights marketed by American, you'll earn miles based on the price paid for your ticket (base fare plus carrier-imposed fees, excluding any government-imposed taxes and fees), multiplied by five (5) for AAdvantage® members. If you reach elite status, you’ll earn award miles at higher rates. Plus, as a Citi® / AAdvantage® credit cardmember or an AAdvantage® AviatorTM MasterCard® cardmember, you will continue to earn additional bonus miles on American Airlines purchases when you use your AAdvantage® credit card.
