AMERICAN AIRLINES GROUP REPORTS

RECORD JUNE TRAFFIC RESULTS

FORT WORTH, Texas – American Airlines Group (NASDAQ: AAL) today reported June and year-to-date 2017 traffic results.

American Airlines Group’s total revenue passenger miles (RPMs) were a record 21.0 billion, up 0.8 percent versus June 2016. Total capacity was 24.9 billion available seat miles (ASMs), up 1.1 percent versus June 2016. Total passenger load factor was 84.7 percent, down 0.2 percentage points versus June 2016.

The company expects its second quarter 2017 total revenue per available seat mile (TRASM) to be up approximately 5 percent to 6 percent year-over-year. This compares to prior guidance which had TRASM up 3.5 percent to 5.5 percent. The improvement in TRASM from prior guidance is driven primarily by higher passenger yields, with particular strength in the Domestic, Central/South American, and Caribbean regions. The company now expects its second quarter pre-tax margin excluding special items to be between 13 percent and 14 percent versus its previous guidance of 12 percent to 14 percent. For more financial forecasting detail, including the company’s anticipated second quarter net special items, please refer to the company’s investor relations update also filed today.

The following summarizes American Airlines Group traffic results for the month ended June 30, 2017, and 2016, consisting of mainline-operated flights, wholly owned regional subsidiaries and operating results from capacity purchase agreements.
