What is the difference between the mileage on my Citi® / AAdvantage® Card statement versus my American Airlines® mileage summary?
The miles shown on your Citi® / AAdvantage® Card statement are the miles earned for that month’s billing cycle for purchases made to your Citi® / AAdvantage® Card. The miles shown on your American Airlines® mileage summary include all miles earned from AAdvantage® Partners and the total accrual of your miles to date.
