Members of Congress have repeatedly introduced bills to ensure the federal employees who control air traffic and conduct airport security screenings get paid during government shutdowns. The Keep America Flying Act. The Keep Air Travel Safe Act. The Aviation Funding Stability Act. None passed in time to keep essential aviation workers from missing paychecks. President Donald Trump on Friday offered a short-term fix for the empty pockets of TSA agents who have gone unpaid since funding lapsed for the Department of Homeland Security in mid-February. Labor unions, airline executives and industry groups are urging Congress to provide a permanent solution by acting on any of the pending pay-protection bills with bipartisan support on paper.
