At the time, Boeing said flyadeal had conducted an evaluation for 50 narrow-body airplanes and had selected the 737 Max for the future. The 737 Max, which promised more seats and lower operating costs than its Airbus competitor, was Boeing's fastest-selling airplane, accumulating more than 4,800 orders worldwide. In April, Boeing reported a $1 billion charge against earnings because of higher production costs for the Max. Analysts expect more charges will follow, including compensation for families and for airlines that have lost the use of the planes until regulators clear them to fly again.
