Philadelphia International Airport's largest airline will reduce its waves of flight arrivals and departures from eight to six.
By collapsing eight banks to six, American Airlines will operate 30 to 40 fewer flights a day in January than it did a year ago. The airline said the move is designed to improve efficiency and boost profits.
The earliest flights will leave the airport at about 8 a.m. instead of 7:30, and the last flights of the day will depart between 8 and 9 p.m. instead of 10 or later.
American has also rebanked its hubs in Dallas-Fort Worth, Chicago and Miami since its 2013 merger with US Airways.
Philadelphia will remain American Airline's fourth-largest hub.
