As the Boeing 737 MAX aircraft remain grounded globally, American Airlines has extended flight cancellations through June 5 at this time, in a bid to provide customers with more certainty and avoid frustration-inducing last-minute flight disruptions.

According to the carrier, the Boeing 737 MAX grounding will lead to the cancellation of around 90 flights per day, based on its current schedule. However, keep in mind not all flights that were previously scheduled on a MAX plane will be canceled. American Airlines will try to substitute other aircraft types instead.

That said, a flight that was not scheduled as a MAX flight might end up getting canceled in a bid to allow for the carrier to operate a MAX route using a different aircraft. American Airlines' goal is to keep the number of affected customers to a minimum.

While nobody wants to be put in a predicament where their flight is disrupted, the 90 or so flights that are cancelled makes up a small portion of flights operated by American Airlines and American Eagle each day - the legacy carrier and its regional airline operate an average of approximately 6,700 flights daily to around 350 destinations across more than 50 countries around the world.

American Airlines wants to be able to offer its customers better service as well as better availability and rebooking options as much as possible. This is what the carrier is aiming to do with the proactive cancellation of all affected flights.

For customers who are impacted by the flight cancellations, they will be contacted directly via email or telephone by American Airlines' Reservations Team.

Like other carriers that are affected by the global grounding of the Boeing 737 MAX aircraft, American Airlines is awaiting the green light from the Federal Aviation Administration (FAA), Department of Transportation (DOT), National Transportation Safety Board (NTSB), other regulatory authorities as well as Boeing to allow for the Boeing 737 MAX aircraft in its fleet to resume flying. American Airlines has 24 MAX planes grounded currently, a fraction of Southwest Airlines' 34 grounded MAX aircraft.
