Ahead of its Q2 2019 financial results, American Airlines is expecting a negative impact of $185 million due to cancellation of Boeing 737 Max flights.
The carrier has cancelled 7,800 flights during the period and has increased the grounding of its 737 Max fleet through 3 September.
American expects to report a 3% to 4% revenue per available seat mile (RASM) gain for the second quarter, exceeding previous guidance of 1 to 3%.
American operated 72.3 billion available seat miles (ASMs) during the second-quarter of 2019, down 1.1 billion than previously guided.
In April, American said it would cost the airline $350 million in pre-tax revenue this year.
American has 24 of the planes in its fleet of more than 900 aircraft and has another 76 on order.
