No, JetBlue and Spirit did not merge. In early 2024, a federal judge blocked the $3.8 billion merger on antitrust grounds, ruling that it would harm competition and raise fares for budget-conscious travelers. Following this ruling, the two airlines officially terminated their merger agreement in March 2024. As of early 2026, Spirit Airlines is operating under Chapter 11 bankruptcy protection and has significantly scaled back its operations, eliminating dozens of routes and laying off staff to restructure its debt. Meanwhile, JetBlue has pivoted to its "JetForward" strategy, focusing on its core strengths in the Northeast and Florida. Interestingly, 2026 market rumors suggest a potential Spirit and Frontier merger might be back on the table, as industry analysts believe the U.S. market may only have room for one dominant ultra-low-cost carrier (ULCC) to survive the current economic climate.
