American Airlines is the latest carrier to extend its ban of the Boeing 737 Max-8 aircraft. The airline, which has cancelled 90 flights a day since the Federal Aviation Administration grounded the aircraft on March 13 after the fatal Ethiopian Airlines disaster, has extended the ban from April 24 through June 5. Southwest Airlines has also extended its ban of the aircraft until at least the end of May. American Airlines issued a statement explaining their reasoning: “In an effort to provide more certainty and avoid last minute flight disruptions, American has extended cancellations through June 5. This will result in the cancellation of approximately 90 flights each day based on our current schedule. By proactively canceling these flights, we are able to provide better service to our customers with availability and rebooking options.”
