Citing rising fuel costs, Delta Air Lines, the third-largest U.S. airline, plans to offer voluntary buyout packages to more than half its 55,000-plus workers. A memo to employees at the Atlanta-based airline states that the company's goal is to cut a minimum of 2,000 frontline, administrative, and management jobs through the buyout program. Multiple news sources also quote a company spokesperson as saying that if more than 2,000 employees agree to the buyout, it will be allowed. In addition, the company is planning to cut its domestic capacity by an additional five percent this year. The Delta memo states that its 2008 fuel bill is expected to increase by nearly $900 million compared to the business plan for this year, which did not take into account the recent rise in oil prices.
