Proponents of long-haul flights at Dallas Love Field have juiced the jets on their lobbying campaign.
And a look at the political calendar may reveal why: Southwest Airlines Co. and its allies could face a closing political window for repealing the Wright amendment.
Even as the mayors of Dallas and Fort Worth hammer out a local deal, a tight election-year congressional calendar will make it hard to take up Wright. Congress is set to take off all of August and adjourn by Oct. 6.
The political landscape could also change.
Polls show Democrats could take over at least one chamber of Congress in the Nov. 7 election. A change in party control could force Southwest to redraw its flight plan.
"That certainly could happen," said Cal Jillson, a political analyst at Southern Methodist University in Dallas.
The limited legislative schedule and shifting political tide favor American Airlines Inc., which operates its largest hub at Dallas/Fort Worth International Airport and opposes any changes to the 1979 law.
American officials say they are cooperating with the mayors.
But privately, they complain about being forced to accept a deal that would favor Southwest. Delaying the process, they say, works to their advantage.
That strategy has drawn criticism from a lead proponent of repealing Wright.
"I have not seen any evidence that American Airlines is interested in sitting down at the table and introducing anything," said Rep. Jeb Hensarling, R-Dallas, who is co-sponsoring a repeal proposal with Rep. Sam Johnson, R-Plano.
Indeed, their sponsorship of the House bill is emblematic of the role that Republicans have played in leading the Wright repeal movement.
GOP Sen. John Ensign of Nevada is the sponsor of a Senate proposal.
"Their core support is mostly in the Republican Party," said a senior American official.
SMU's Mr. Jillson said Southwest and its allies also are motivated by a sense they are making progress. The mayors of Dallas and Fort Worth are working on a plan to lift restrictions at Love -- not to close the city airport and force Southwest to move to D/FW, as American has suggested.
"Southwest feels like the ball is moving, and they would be crazy not to keep it moving," Mr. Jillson said.
Dallas Mayor Laura Miller set a June 14 deadline to produce a plan, and Fort Worth Mayor Mike Moncrief set Aug. 1.
Tom Chapman, Southwest's Washington legislative counsel, said Southwest stood down for 30 days to give the mayors time to negotiate. But now, he said, it's time to take advantage of the renewed momentum.
Mr. Chapman downplayed the consequences of a change in majority power on Capitol Hill, noting both the House and Senate proposals to repeal Wright have Democratic co-sponsors. And although the airline supports the local negotiations, he added: "It is such a difficult controversy, we feel we have to bring that energy level to it. We cannot put all our eggs in one basket."
But if the Democrats take control of the House or Senate, others believe Southwest's momentum could stall.
At the very least, the airline would have to retool the effort it launched in 2004 to repeal Wright.
"Part of all their fury is that they are reading these tea leaves," the American executive said.
For starters, the leadership of key committees would change with a Democratic majority.
In the House, the Transportation Committee is chaired by Rep. Don Young, R-Alaska. Mr. Young is blocking Wright-related initiatives but has indicated he is willing to act on a proposal if North Texas lawmakers find a compromise.
If the Democrats took control of the House, Mr. Young likely would turn the gavel over to Rep. Jim Oberstar, D-Minn., who opposes the current repeal campaign.
It is likely that Mr. Hensarling would have to look for a Democrat to become a lead co-sponsor.
The limited legislative schedule and shifting political tide favor American Airlines, which opposes any changes to the 1979 law.
Identical bills to implement the agreement are set to be introduced as early as Thursday in the House and Senate.
The resolution would effectively force American to accept eventual repeal of the 1979 Wright law.
