When you place a qualifying online order through the AAdvantage DiningSM site, you will earn American Airlines AAdvantage® miles at your current earning rate only on the subtotal. This means that you won’t earn AAdvantage® miles on tax, tip, and/or delivery-related fees for online orders.
However, when you dine in at a participating program restaurant, you will earn AAdvantage® miles on the final bill amount, including tax and tip.
