Delta Air Lines subsidiary Comair is cutting 300 pilots and 220 flight attendants from its staff.

The layoffs will go into effect when Comair cuts its flight schedule in September as part of Atlanta-based Delta's capacity cuts. The move will affect crew members based at New York's John F. Kennedy International Airport and at Cincinnati/Northern Kentucky International Airport.

Erlanger, Ky.-based Comair has 6,300 employees, including 1,477 pilots and 940 flight attendants. The airline has already cut more than 6 percent of its administrative staff since January, Comair spokesman Jeff Pugh said Tuesday.

The cuts are part of Comair's plan to cut flying by about 15 percent starting in September and trim 14 aircraft from its fleet of 128 planes.
