After two Boeing 737 Max 8 jets crashed within five months of each other there have been public questions about the future of the aircraft while major airlines scale back on flights amid investigations from federal regulators.

American Airlines said on Sunday that it will cancel 90 flights a day for most of April due to the FAA's recent decision to ground all 737 Max 8 flights after the March 10 crash of an Ethiopian Airlines flight that killed all 157 on board and the Lion Air crash in October that killed all 189 passengers. American Airlines had previously only canceled flights through March 28.

"In an effort to provide more certainty and avoid last minute flight disruptions, American has extended cancellations through April 24," American Airlines said in a statement.

However, not all the flights being grounded were Max 8 flights. Instead, the cancelations are going be a mix of those flights and other flights that were not using the Max 8 jets. Doing so will allow American to reassign other aircrafts to still scheduled flights that would originally be onboard a Max 8.

The idea with this model, American explains, is to try and limit the impact of the cancelations to as small a number of customers as possible.

But if a flight was canceled, "American's Reservations team will contact affected customers directly by email or telephone."

The Texas-based airline did say it would work to reschedule flights or, if a customer desires, request a full refund for the canceled flight.

American Airlines isn’t the only major carrier canceling flights. Southwest Airlines is making cancelations five days in advance, averaging 130 daily cancelations, according to reports.
