Airlines Had the Perfect Conditions for Jacking up Fares. Then Spirit Collapsed
Airfares were about 15% higher in March, and analysts said Spirit’s exit could lift prices further as low-cost competition fades.
Spirit Airlines has closed, removing a major low-cost competitor from the U.S. market and raising concerns that domestic travelers will face higher ticket prices as competition shrinks.
Researchers have identified the so-called "Spirit effect," finding that major airlines compete more aggressively on lowest fares when ultra-low-cost carriers like Spirit and Frontier are present in the market.
A Business Insider analysis of Cirium data found airfares rose about 14% on roughly 90 routes Spirit exited in 2024 and 2025, versus about 6% to 7% where Spirit continued operating.
Clint Henderson, managing editor at The Points Guy, told NewsNation travelers should expect higher costs, especially in Fort Lauderdale, Orlando, Las Vegas, and Detroit where Spirit had major presence.
Carriers are moving to fill the gap: JetBlue plans to add 11 destinations from Fort Lauderdale, while budget carrier Breeze Airways is adding routes from Atlantic City to offset impacts.
