Northwest Airlines plans to remove one-fourth of its old DC-9s from its fleet in 2008, but it does not intend to cut any pilot jobs.
The Eagan-based carrier said that it expects to increase the use of the remaining planes in its fleet and hire 200 to 250 pilots by the year's end.
Northwest spokesman Roman Blahoski said Friday that additional flying with other aircraft "is projected to more than offset the reduction in required DC-9 staffing."
Northwest's fleet of DC-9s is expected to drop from 92 in 2007 to 68 by the end of this year.
The airline is accelerating the removal of the DC-9s from its fleet. Ten months ago management intended to keep 78 of them through this year.
Northwest also will take three 747-200s out of operation this year.
"Everybody is evaluating fleet in the face of current oil prices," said William Swelbar, a research engineer at the Massachusetts Institute of Technology.
For Northwest, Swelbar said, it is more fuel-efficient to shift some DC-9 flying to Northwest's Airbus A319s and A320s as well as to new 76-seat Embraer and Bombardier regional jets flown by its regional subsidiaries, Compass and Mesaba airlines.
