Spirit Airlines abruptly canceled all flights early Saturday, leaving travelers scrambling to make alternative arrangements. Passengers described scenes of chaos at airports as the budget carrier's sudden shutdown became apparent. Some travelers had already boarded planes before learning their journeys would not proceed as planned.

Many affected passengers were in the middle of their trips when the cancellations occurred, disrupting vacation plans and business travel alike. "Even if they go back into business, never again," said one stranded traveler, reflecting the frustration felt across terminals. The carrier's collapse marks another chapter in the U.S. airline industry's recent turbulence.

The shutdown leaves thousands of passengers without immediate refunds or clear recourse for rebooking on competing carriers. Spirit, once known for its ultra-low-cost model, joins a list of carriers that have ceased operations in recent years. Travelers face limited options during what is typically a busy travel period, with other airlines potentially raising prices amid increased demand.
