14 Airlines Most Likely to Cancel Your Flight (And How to Avoid Them)

9. Allegiant Air – Limited Flexibility and High Cancellations

Allegiant Air, known for its low-cost, leisure-focused flights, experiences high cancellation rates due to its limited flight schedule and fleet size. The airline's strategy of operating fewer flights with less frequent service leaves little room for recovery when disruptions occur. Passengers are encouraged to book flights with ample time before important events and to explore refundable options or travel insurance to ensure their travel plans are protected against unexpected cancellations.
