UAL Corp.'s United Airlines, which emerged from bankruptcy Feb. 1, will cut another 1,000 salaried and management jobs by year's end to further lower its costs. The 11 percent reduction will help the world's second-largest airline pare administrative expenses by about $100 million, Chief Executive Officer Glenn Tilton said Wednesday. United wants to trim total spending by $400 million this year. United announced the new savings target May 8, saying spending on jet fuel and labor boosted first-quarter costs by 3 percent.
