The flight disruptions during the record government shutdown that ended last week inspired a rare act of bipartisanship in Washington on Tuesday, when congressional representatives from both parties introduced legislation that would allow air traffic controllers to get paid during future shutdowns.

The bill proposes funding salaries, operating expenses and other Federal Aviation Administration programs by tapping into a little-used flight insurance fund that was created after the Sept. 11 attacks and currently has $2.6 billion dollars sitting in it. The bill's sponsors, which include four of the top Republicans and Democrats on the House Transportation and Infrastructure Committee, hope that relying on the fund might make their bill more attractive than other proposals because it would limit the potential cost of dolling out paychecks.

GOP Rep. Sam Graves, chairman of the committee, said in a statement that the bill would help keep the traveling public safe during future shutdowns. The other sponsors include Democrats Rick Larsen and Andre Carson along with Republican Troy Nehls, who leads the aviation subcommittee.

"We all saw that the system can be vulnerable when Congress can't get its job done," Graves said. "This bill guarantees that controllers, who have one of the most high-pressure jobs in the nation, will get paid during any future funding lapses and that air traffic control, aviation safety, and the traveling public will never again be negatively impacted by shutdowns."

The bill's introduction comes ahead of a scheduled hearing Wednesday by a Senate subcommittee to examine the impacts of the 43-day shutdown on aviation.

But it's not clear whether this bill -- or any similar proposals that have been floating around Congress since the 2019 shutdown -- will have a chance to get approved before the next government funding deadline at the end of January. Nearly all the other proposals, including one from U.S. Sen. Jerry Moran, would rely on the aviation trust fund that collects money from fees the airlines pay, and the Congressional Budget Office has given those bills a much higher price tag.

Over the years, lawmakers have tried a handful of fixes for a long-term solution to keep air traffic controllers and other essential aviation workers paid during funding lapses. The proposals often gained bipartisan attention, especially after the 35-day shutdown that ended in 2019 during Trump's first term, but none made it over the finish line.

Moran's bill, known as the Aviation Funding Stability Act, for example, is a recurring proposal in Congress that would allow the FAA to tap into the Airport and Airway Trust Fund. Lawmakers in both chambers have reintroduced versions of it over the years, including in 2019 and 2021.

The legislation resurfaced in March when Moran, the Republican chairman of the Senate subcommittee on Aviation, Space, and Innovation, put it forward. It came up again in September, weeks before the shutdown began, when Reps. Andre Carson and Steve Cohen, both Democrats, introduced it in the House.

The new bill introduced Tuesday would cut off the money if the insurance fund dips below $1 billion. But Transportation Committee staffers estimate that would still provide enough funding to keep FAA operating for four to six weeks.

The issue gets so much attention because of all the flight delays and cancellations that happen during a shutdown when more air traffic controllers call out of work. The existing shortage of controllers is so severe that just a few absences in an airport tower or other FAA radar facility can cause problems.

The controllers -- and the FAA technicians who maintain the equipment they rely on -- are expected to continue working without pay during a shutdown to keep flights operating. But as the financial pressure mounted, some controllers picked up second jobs and may have taken time off to make some cash driving for Uber or DoorDash.

The delays got so bad during this fall's shutdown that the government ordered airlines to cut some of their flights at 40 busy airports nationwide, in what the FAA said was a move to relieve pressure on the system and controllers. Thousands of flights were canceled before the FAA lifted the order entirely and airlines were able to resume normal operations Monday.

The insurance fund the bill introduced Tuesday would use was created at a time when airlines were having trouble getting any insurance coverage after 9/11. For years, airlines paid into the fund regularly to get coverage from the government.

But by the early 2010s the insurance market for airlines had stabilized. Congress let the insurance program expire at the end of 2014. The fund still exists today to pay for claims an airline might file if the government commandeers one of its planes for a military operation or other use.

The last time a claim was made was after America's withdrawal from Afghanistan in 2021. The fund has continued to grow as it collects interest.
