Allegiant Air surges back into headlines with a Sun Country merger cash-and-stock deal worth ~$1.5B, expanding its ultra‑low-cost network.
Spirit Airlines has ceased operations due to mounting losses and fuel-cost pressures, prompting consolidation in the U.S. budget-airline sector. Allegiant’s merger with Sun Country closes, expanding its network while maintaining separate brands for now. The industry faces higher jet-fuel costs, fuel-related fare hikes, and route reallocation as airlines recalibrate post-Spirit.
