Executives at Northwest Airlineshave proposed that Northwest and Delta Air Lines go ahead with a planned merger, a source familiar with the talks said Friday.
The news may revive speculation that Delta, the No. 3 U.S. airline, and Northwest, the No. 5 U.S. airline, could merge to form the world's largest airline. Some industry watchers believe a Delta-Northwest merger would trigger a wave of consolidation in the industry.
Both Northwest and Delta declined to comment.
Northwest shares rose 3.55 percent to $8.76 on the New York Stock Exchange Friday, while Delta shares finished 3.11 percent higher at $8.61.
The airlines have held merger talks that seemed to fizzle after their pilots' unions failed to agree on plan to integrate their seniority lists.
The Wall Street Journal reported on its Web site that Northwest's proposal suggests offering pilots less generous terms than previously offered.
Both pilot groups are represented by the Air Line Pilots Association (ALPA). Delta's ALPA chapter had no immediate comment. Northwest's ALPA chapter did not return a call seeking comment.
"Basically, unless Delta management has a change a heart, I don't think they're going to do anything without the support of their pilots,'' said Calyon Securities analyst Ray Neidl. "It shows that people don't want it to die and they'll keep trying things, but I don't think it puts us any closer.''
Many airline experts, including leaders of top U.S. carriers, say mergers should help stabilize the hard-hit industry, which finally emerged from a five-year slump in 2006 after racking up $35 billion in losses. But soaring fuel prices and a softening U.S. economy are threatening to stunt the fledgling recovery.
