A prominent UK low-cost carrier was identified by the Flighty tracking app as the world's most delayed airline throughout 2025.

Key Points

1A UK low-cost carrier was designated the world's most delayed airline in 2025, according to data compiled by the Flighty tracking application.
2The ranking analyzed millions of global passenger journeys, confirming that flight delays remain a significant operational problem for the sector.
3Operational performance was severely impacted by factors including European ATC strikes, airport congestion, and scheduling pressures inherent to the budget carrier model.

The Flighty flight tracking application has released its comprehensive annual analysis of global on-time performance, designating a major UK low-cost carrier as the world's most delayed airline throughout the 2025 calendar year. This finding is based on the meticulous study of millions of passenger journeys worldwide, underscoring significant operational challenges within the highly competitive European budget sector. The report highlights that flight delays continue to be a major source of disruption for travelers, particularly during high-demand periods.

Operational data suggests that the poor performance of the UK carrier was exacerbated by external factors common across the industry, including widespread air traffic control (ATC) strikes across the European continent and persistent airport congestion at key hubs. However, the high utilization model characteristic of low-cost carriers means that minor disruptions quickly cascade, leading to systemic delays that impact overall schedule reliability and passenger experience. The data serves as a critical indicator of the strain placed on global aviation infrastructure and carrier scheduling in the post-pandemic recovery environment.
