American Airlines says it is “proactively” cancelling 90 flights each day between now and April 24 due to the grounding of its fleet of 24 Boeing 737 Max aircraft.

CNBC reports that the airline said cancelling the flights while awaiting a decision from the US Federal Aviation Administration on whether the troubled Boeing jets can fly again would help customers by providing more rebooking options.

“We know these cancellations and changes may affect some of our customers, and we are working to limit the impact to the smallest number of customers,” according to a statement from American.

The 737 Max fleet was grounded worldwide after a pair of crashes that investigators worry could be related to the flight-control software installed on the jets. An Ethiopian Airlines 737 Max crashed on March 10, killing 157 people, and a Lion Air 737 Max crashed in Indonesia on October 29, killing all 189 passengers and crew members.

The airline said it is contacting customers affected by the cancellations via phone and email.
