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

17. Vueling Airlines – Budget Carrier, Unpredictable Performance

As a low-cost carrier based in Spain, Vueling is infamous for last-minute cancellations, especially during peak summer months and holiday rushes. Operational issues and limited staff flexibility mean even small disruptions (weather, staff illness, etc.) can spiral into major delays. Since Vueling often doesn’t offer immediate rebooking on other airlines, travelers can get stuck for hours—or days. Choose earlier flights when schedules are fresher, and avoid routes with just one daily departure. If possible, spring for flexible fare classes to give yourself more leverage if things go south.
