Delta Air Lines' ( DALR) regional unit Comair is aiming to lower its costs by up to $70 million a year through cutting jobs, reducing the size of its fleet and scaling down pay.

Comair will end some aircraft leases and mortgages to reduce ownership costs. Delta, which filed for bankruptcy protection in September, plans to remove up to 30 aircraft from Comair's schedule.

Additionally, Comair will do away with up to 1,000 jobs throughout the company, including the reduction of around 350 positions already announced. The carrier will also cut pay for officers and directors and for nonunion employees.

Comair is scheduled to begin talks with union representatives for pilots, flight attendants and mechanics as it bids to reduce its labor costs.

Based at Cincinnati/Northern Kentucky International Airport, Comair has been a Delta regional carrier since 1984. The airline operates 1,155 flights a day to 110 destinations in the U.S., Canada and the Bahamas.
