Facing high fuel costs and a softening economy, Northwest Airlines said Thursday it will cut its domestic flight schedule by 5 percent this fall.
The Eagan-based carrier did not announce layoffs. It said it hopes to cut jobs through attrition.
"Over the past several months, the price of oil has risen dramatically to all-time highs, and there is no reasonable basis to conclude that oil prices will materially decline anytime soon," Northwest CEO Doug Steenland said in a written statement. "These increased costs are significant and call for a strong response from us."
Northwest plans to take 15 to 20 airplanes out of service, beginning with two old, fuel-guzzling DC-9s in June.
The sharp rise in fuel prices is forcing airlines big and small to adjust their business plans on the fly in order to boost revenue and trim operating costs.
On May 1, Northwest also is increasing a fuel surcharge on flights from Japan. Last week, it matched competitors in charging $25 for passengers who check a second bag.
Northwest's decision to reduce its U.S. flying follows two large rivals -- Delta Air Lines and United Airlines -- that also chose to shrink their fleets.
With more than $3 billion in cash on hand, Northwest is positioned to ride out the financial threat caused by oil that's exceeded $100 a barrel in recent weeks.
