American Airlines cuts its year-long profit forecast, charging roughly $ 350m over grounding its Boeing 737 Max.
The airline has canceled 15,000 flights using its twenteen 737 max aircraft by the end of August.
Aviation Regulators around the world founded the 737 Max fleet after two crashes on a plane killed 346 people.
American Airlines said it was confident that the aircraft would continue to fly in August.
Before that happens, Boeing's manufacturer of aircraft has to develop a software fix for 737 Max and a new pilot training for regulatory approval from the Federal Aviation Administration of the United States.
American Airlines also said that the cost of fuel for the year now will be $ 650 million more than previously expected, due to rising oil prices.
The largest airline in the United States by the passengers they carried, said it now expects the adjusted profit from 2019 to fall between $ 4 and $ 6 per share, down from $ 5.50 to $ 7.50 per share.
For the first quarter, which was not completely affected by the grounding of 737 Max aircraft, the net profit was $ 185 million, which is $ 159 million for the same period in 2018.
