Budget airline Allegiant expands its network after Spirit’s collapse, driving a cheaper, simplified route map while travelers watch miles and perks shrink this summer.
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.
