Denver's two largest airlines will cut an additional 130 local jobs in coming months as part of previously announced plans to counter high fuel costs.

Frontier Airlines - the second-largest carrier at Denver International Airport - plans to slash 113 positions on Sept. 9, according to a letter it sent to state officials.

That comes on top of 456 local positions the Denver-based carrier has said it will cut this fall, bringing its total to 569.

Frontier also is reducing jobs in some other cities, including 37 in Las Cruces, N.M., company spokesman Steve Snyder said.

United Airlines - Denver's largest carrier - plans to eliminate another 17 pilot positions at DIA in September and scrap 14 more daily departures in November.

The carrier detailed the additional job cuts in a letter to the Colorado Department of Labor and Employment. It revealed information about the capacity reduction in a message to employees.

The two airlines, which hold a combined 75 percent of the market at DIA, recently announced plans to cut flights and jobs but did not initially provide details.

Frontier filed for Chapter 11 in April and is trying to secure financing to emerge from bankruptcy.

The carrier intends to reduce mainline capacity by 17 percent and ground seven planes. It has said those efforts also will include a "proportional reduction" in jobs.

The 586 local layoffs it has revealed so far account for 12 percent of the company's 4,788 workers in Colorado.

"I do not know if this is the last of them or not," Snyder said on Monday.

The first group of layoffs involves flight attendants, mechanics, customer service agents and other employees who work at DIA.

The second group "encompasses the rest of the organization," Snyder said, and includes workers in reservations, training, customer service, human resources, safety and accounting.

United's move to eliminate 17 pilot jobs at DIA comes as the carrier cuts 150 local positions this month.

It also will reduce the number of daily flights it operates between Denver and 14 cities, including big markets such as Atlanta, Chicago and Los Angeles and smaller towns such as Vail, Montrose and Fargo, N.D.

Additionally, United plans to end its one daily departure from the Mile High City to Charlotte, N.C.

The reductions - effective in November - bring United's planned daily flight cuts this fall in Denver to 43.

United said it will have 370 daily departures at DIA in November, an 11 percent drop from the same month in 2007.

The moves are part of United's plans to trim about 14 percent of its capacity by the fourth quarter.

United spokeswoman Megan McCarthy said the company has announced most of the reductions planned for this year.

The Chicago-based airline, however, has yet to reveal details of additional cuts for next year.
