Thousands of US flights canceled, delayed for third day in a row
XLY•More than 10,000 US flights were canceled or delayed on Sunday, the third day of disruptions. Transportation Secretary Sean Duffy predicted air travel would be fully back to normal by Monday, though the cause of the router problems remains unknown.
1. Disruptions continue
More than 2,300 flights were canceled and about 7,700 delayed across the United States on Sunday. Airlines had canceled more than 6,400 flights and delayed more than 8,000 on Saturday.
2. Router problems traced
The FAA said router issues followed the replacement of equipment at facilities in El Dorado, Arkansas, and Amarillo, Texas, and overloaded communications systems at other air traffic control centers. The agency disabled the functionality of the originating routers and about 60 similar routers, but Duffy said officials did not know the root cause. He said there was no evidence of a cyberattack or other malicious intent.
3. Calls for investment
Duffy called for $50 billion to upgrade air traffic control systems, up from his earlier request of $30 billion. Representatives Rick Larsen and André Carson said about $11 billion of the $12.5 billion approved in 2025 for system upgrades remained unspent. Airports Council International director general Justin Erbacci also called for private investment in air transport infrastructure.
