American Airlines says it is cutting 2% of flights from its schedule in September and October.

American calls the cuts "proactive adjustments" in order to "size our airline for the resources we have available and to build additional buffer into the remainder of our summer schedule."

At its hub in Philadelphia, American will cut hundreds of flights -- roughly 3% of September flights scheduled and 5% in October.

Airlines have been struggling with staffing shortages, summer weather and air traffic control delays as passengers are returning to pandemic-era travel in droves.

The cuts are the latest in a series by airlines in the United States to ease air traffic disruptions this summer.

United Airlines cut its schedule by 12% this summer at Newark Liberty International Airport, which has been plagued by cancellations and delays. Delta Air Lines also "strategically decreased" flights this summer.
