More than 5,000 American flights faced cancellation or delay on Friday as the government shutdown forced emergency cuts to air traffic nationwide. The Federal Aviation Administration mandated a 4% reduction at 40 major airports, set to escalate to 10% next week and potentially 20% if the crisis continues.

Air traffic controllers, working without pay for over a month during America's longest government shutdown, triggered the unprecedented action. Essential workers have been calling in sick or taking second jobs whilst managing stress-related illnesses, creating severe staffing shortages at major hubs including New York, Los Angeles, Chicago and Washington DC.

The mandate upended travel plans across the country. Joe Sullivan missed his cousin's wedding after his Atlanta flight was cancelled, receiving rebooking 12 hours later. One desperate woman purchased a $300 train ticket as backup for her hour-long flight. Airlines including Delta, United and American offered full refunds and fee waivers to affected passengers.

Nick Daniels, president of the National Air Traffic Controllers Association, described workers as 'political pawns' in the congressional standoff.

"We cannot suddenly put money in our own pockets," he told media. "We need Congress to open the government."

Transportation Secretary Sean Duffy confirmed international travel remains unaffected due to existing agreements, though domestic chaos could worsen significantly. The 38-day shutdown shows minimal progress on Capitol Hill, with Democrats and Republicans deadlocked over healthcare subsidies and funding measures requiring 60 Senate votes.
