MINNEAPOLIS -- Wall Street sure would like to see United Airlines and US Airways combined into one airline. Travelers? Maybe, maybe not.
The general thinking among analysts is that the U.S. has too many big carriers offering too many seats. That drives down ticket prices and makes it harder for airlines to turn a profit. US Airways and United lost a combined $856 million last year. Airline investors like consolidation because they expect it would lead to fewer seats and thus higher fares.
Which is where travelers start to get antsy.
"Mergers tend to be a net negative for consumers," said Tim Winship, the editor of FrequentFlier.com.
A combined United-US Airways would be the nation's second biggest carrier, behind only Delta Air Lines Inc. Combining them "would inevitably result in a significant loss of competition, the predictable result of which would be an increase in airfares in certain markets," Winship said.
The two airlines are major carriers in Washington, although that market also has extensive service from discount carriers.
Also, both serve Charleston International Airport. US Airways offers more than dozen local daily flights to four destinations: Charlotte, New York, Philadelphia and Ronald Reagan Washington National Airport outside the nation's capital. United, through its United Express carrier, provides service to hubs in Chicago and Washington Dulles International Airport in northern Virginia.
Kathy Torino, manager at Travel Leaders in North Charleston, said a merger could translate to higher fares for local travelers.
"The less airlines you have the less competition you have. It's always cause for concern," Torino said. "Especially for us because some of the major hubs have a lot more major carriers to choose from."
UBS analyst Kevin Crissey wrote that he thinks a major combination such as United-US Airways would reduce capacity as much as 3 percent, mostly in the U.S. With fewer seats and competition, fares should rise, he wrote.
The airline industry is a mess, he wrote, with no major U.S. airline earning a profit that justifies the size of its investments.
"Consolidation, though not easy, riskless, or free, is a logical way to attempt to rectify this long standing problem," he wrote.
U.S. carriers all reduced capacity last year, and fares fell anyway, because of the recession and especially a dropoff in business travel demand.
Shares of both carriers closed higher Thursday, with Tempe, Ariz.-based US Airways Group Inc. up 73 cents, or 10.3 percent,to $7.55. Chicago-based United's parent, UAL Corp., rose $1.28, or 6.8 percent, to $20.23.
Both carriers have tried for combinations in the past. United chairman and chief executive officer Glenn Tilton and US Airways chairman and Chief Executive Officer Doug Parker were involved when their companies talked about a tie-up in 2008. They walked away then citing high fuel prices but didn't rule out a future deal. That same year, Continental Airlines Inc. rejected United's attempt at a combination.
Neither airline has confirmed the talks. On Thursday, United's president, John Tague, wrote to employees about what he called the "speculation regarding a possible merger between US Airways and United."
"As is our practice, we will not add to any speculation by commenting on rumors," he wrote.
