Northwest shares began trading on the New York Stock Exchange this morning, with CEO Doug Steenland and other employees ringing the opening bell, marking the end of a wave of airline bankruptcies that began after the Sept. 11 attacks. The shares traded at $25.25 after being offered to unsecured creditors at $27.

Northwest has slashed debt by $4.2 billion, cut $400 million a year in the cost of its fleet, and trimmed unprofitable rou
y of Northwest Airlines," Steenland said in a prepared statement. "We have successfully repositioned the company as a stronger, globally focused airline with a great route network, a revitalized fleet, a competitive cost structure and a recapitalized balance sheet."

"We believe that we have a viable business plan that will continue to deliver profits in the future," he said.

Northwest, which has had the oldest fleet of U.S. airlines, will be upgrading it over the next two years. It will be the first North American airline to take Boeing's new 787 "Dreamliner."

It also plans to add 72 regional jets which include a first-class section, adding the number of first-class seats Northwest offers. The new 76-seat jets will fill an empty spot in Northwest's fleet between its smaller regional jets and its old DC-9s, which generally have around 1
of the airline industry, Northwest has been on a roller coaster the past decade.

On Sept. 10, 2001, the airline industry was coming off the 1990s economic boom, as business travel rose and fuel prices stayed low. U.S. airlines raked in around $5 billion a year in profits from 1997 through 1999 and almost $2.5 billion in 2000, according to government statistics compiled by the Air Transport Association.

But Sept. 11, the slowing economy, and the run-up to the Iraq war hurt business travel, and rising fuel prices hurt airline profitability.

Northwest was also hurt by the SARS scare in Asia, where it and UAL Corp.'s United Airlines are the two largest U.S. carriers. Eagan-based Nor
orthwest's costs were higher than every other airline except U.S. Airways Group Inc., according to government figures. By the end of 2006, when most of the airline restructuring was finished, Northwest's costs were lower than those at U.S. Airways, Delta, and Continental Airlines Inc., though still higher than costs at AMR Corp.'s American Airlines and arch-competitor United.

One advantage Northwest will have is that its new labor contracts lock workers into lower pay rates and more company-friendly work rules through the end of 2011, longer than any of its U.S. competitors.
