United Airlines CEO Scott Kirby has branded the ultra-low-cost carrier model a “failure.” Spirit Airlines, currently in bankruptcy proceedings, responded by declaring that it will “keep flying for many years to come.”

Striking Remarks at Aviation Summit

Speaking at the U.S. Chamber of Commerce Aviation Summit in Washington, United Airlines CEO Scott Kirby sharply criticised Spirit Airlines’ business model.

“The ultra-low-cost carrier business model was an interesting experiment that failed. It doesn’t seem very likely to me that Spirit will keep flying when its customers don’t like the airline and don’t want to fly with it,” Kirby said.

Immediate Response from Spirit

Spirit Airlines swiftly responded on social media platform X.

“Our customers value affordable fares and exclusive offers. Perhaps that’s why United executives can’t stop talking about us,” the airline said.

Bankruptcy and Market Share Struggles

Spirit Airlines filed for bankruptcy last month for the second time in a year. Its previous restructuring process had not been enough to strengthen its financial standing.

The airline suspended flights in 11 cities, including Portland and San Diego.

Although it generated $1 billion in revenue last quarter, it reported $1.2 billion in expenses.

These developments have eroded Spirit’s market share, opening new opportunities for competitors.

United’s Strategic Move

United Airlines has launched ticket sales on new routes to 15 cities previously served by Spirit. The company described the move as “offering alternatives to Spirit customers.”

Spirit, however, dismissed the initiative as “wishful thinking,” stressing that it will continue operations for many years ahead.

Competition Heats Up in Aviation

Kirby’s remarks and Spirit’s financial troubles once again highlight the intensifying rivalry in the U.S. airline industry. Experts note that the future of the low-cost carrier model is facing a major test, particularly in the American market.
