Aviation regulators around the world grounded the planes in mid-March after two deadly crashes. Boeing developed a software fix for the planes after an anti-stall system on board was implicated in both crashes. However no decision was assumed yet to allow Boeing 737 MAX to flight. Boeing executives, FAA engineers and international aviation regulators have steadily expanded their safety analyses to cover a growing list of issues spanning everything from emergency recovery procedures to potentially suspect electronic components. American Airlines said the removal of the planes from its schedule through Nov. 2 would lead to approximately 115 canceled flights a day.
Even when Boeing gets clearance to fly the plane again, American will need about 30 to 45 days to provide its more than 4,000 Boeing 737 pilots with the additional required training. In fact, 737 MAX planes are unlikely to be ready to carry passengers again until 2020 Travelers holding tickets for flights on American or United this fall should check their tickets for possible cancellations or changes. People whose flights are affected will be rebooked or can request a refund if their flight is canceled. Airline executives say that most travelers do not book their travel this far in advance, so the number of passengers affected is not significant.
