(CNN) -- American Airlines is extending flight cancellations into early June because of the Boeing 737 Max grounding.
American, the world’s largest airline, said Sunday it will cancel about 90 flights daily through June 5. American had previously canceled flights through late April.
“By proactively canceling these flights, we are able to provide better service to our customers with availability and rebooking options,” American said on its website. Customers that are affected will be contacted by American and given options for another flight.
The airline has 24 737 Max jets in its fleet. American said it is still waiting for more information from the Federal Aviation Administration, Department of Transportation, National Transportation Safety Board and other regulatory authorities before resuming flights.
Boeing’s 737 Max planes were grounded indefinitely in the United States on March 13 after two of the planes had fatal crashes. A Lion Air flight crashed in October and an Ethiopian Airlines flight crashed on March 10.
Other countries had already suspended the planes immediately following the Ethiopian Airlines crash.
