NEW YORK (AP) - American Airlines is canceling 115 flights per day through mid-August because of ongoing problems with the Boeing 737 Max aircraft.

  

The cancellations represent 1.5% of American's total flights each day of the summer.

  

The U.S. grounded Boeing's 737 Max plane in mid-March after two deadly plane crashes. Boeing aims to finish fixing the planes in late April, and changes would have to be submitted to the Federal Aviation Administration and foreign regulators for approval.

  

American has 24 Max jets and had previously planned to cancel Max flights through early June. Airline officials say by extending cancellations through the summer they can plan more reliably for the peak travel season.

  

The airline says its reservations and sales teams will work with customers to manage their travel plans.
