The heads of the most important airways within the nation penned an open letter Wednesday calling on Congress to fund a serious modernization of the U.S.’s antiquated air visitors management system that has contributed to heightened security considerations and rampant airport delays.

“The current system is failing Americans,” the group of 10 firm CEOs wrote in a joint letter that was posted on the Airways for America (A4A) business collective’s web site. “The United States needs and deserves a world-class aviation system.”

A4A represents American Airways, Delta, United, Southwest, JetBlue, Alaska Airways, Hawaiian Airways and Atlas Air, in addition to international delivery corporations FedEx and UPS.

Representatives from the airways have been holding common conferences with the Federal Aviation Administration (FAA) in current weeks to debate varied considerations and steps ahead to deal with them.

“Commercial airline travel remains the safest form of transportation in world history,” FAA Performing Administrator Chris Rocheleau stated in an announcement Wednesday. “But the last three months drove home that we need to do more, we need to be better, and we need to do it together.”

The FAA issued an interim order on Tuesday lowering the flight arrival and departure charge at Newark Liberty Worldwide Airport in New Jersey, after staffing and tools points spiraled into mass delays.

“Our goal is to relieve the substantial inconvenience to the traveling public from excessive flight delays due to construction, staffing challenges, and recent equipment issues, which magnify as they spread through the National Airspace System,” Rocheleau stated.

Transportation Secretary Sean Duffy has been on an aggressive push to resolve a long-standing air visitors controller staffing scarcity, however outdated tools has compounded considerations lately.

The airline corporations wrote of their joint letter that it is on Congress to pay for a brand new multi-billion-dollar, state-of-the-art air visitors management system.

“Aviation is an industry of innovation, and the FAA needs the ability to procure 21st century equipment and transformational technology solutions to efficiently and strategically handle 21st century flight volumes,” they wrote.

Republicans, who maintain slim majorities within the Home and Senate, try to hash out a spending plan for the approaching 12 months that can cowl most of President Trump’s sweeping coverage agenda in what Trump has dubbed the “One Big, Beautiful Bill.”

The Home Finances Committee’s model of the reconciliation invoice consists of simply over $12 billion for the FAA know-how improve, which the airways deemed a “solid down payment” towards the total overhaul wanted.
