American Airlines announced Sunday that it will cancel all Boeing 737 Max-8 flights through Aug. 19, Reuters reports. The airline currently owns 24 737 MAX-8 jets, and is expecting 16 more this year; Reuters reports that the cancellation will impact about 1.5 percent of AA’s daily flight schedule. Chief Executive Doug Parker and President Robert Isom said in a letter that the decision was intended to “provide confidence to our customers and team members when it comes to their travel plans.” The move comes approximately a month after a Boeing 737 Max Ethiopian Airlines plane crashed shortly after takeoff and killed all 157 people on board, and months after a Lion Air plane of the same model crashed in October and killed 189. Both planes allegedly had problems with Boeing’s flight control system. Boeing’s engineers are now working on a solution to that problem.
