AirAdvisor reveals Europe’s worst-performing airlines based on 2025 passenger data

NEW YORK, NY – AirAdvisor has released its ranking of the worst-performing European airlines for 2026, based on a comprehensive analysis of airline performance during 2025. The study aims to help passengers make more informed booking decisions amid ongoing issues with delays, cancellations, and service quality.

The ranking evaluates more than 150 airlines operating across Europe using nine criteria: flight reliability, onboard comfort, safety record, ticket affordability, customer reputation, airport lounge quality, professional airline recognition, family travel policies, and pet travel policies.

According to the analysis, reliability continues to be the most significant source of passenger dissatisfaction. Airlines at the bottom of the ranking consistently recorded poor on-time performance and higher disruption rates, confirming that delays and cancellations remain the primary drivers of negative travel experiences.

The findings also indicate that ultra-low-cost carriers tend to score well on affordability but perform poorly on comfort, customer reviews, and family or pet travel policies. This reinforces the trade-off between lower fares and overall travel experience.

Customer reputation emerged as a critical factor in the rankings. Airlines with the weakest results showed persistently low review scores, reflecting ongoing issues with service quality, communication, and disruption management.

The analysis further notes that full-service carriers are not immune to poor performance. Several legacy airlines appeared in the bottom ten due to inconsistent service levels, high pricing, or underperforming lounge offerings.

Safety standards across European airlines were found to be broadly aligned, reducing their impact as a differentiating factor. As a result, passenger experience elements such as reliability, comfort, and value for money played a more decisive role in the rankings.

Anton Radchenko, CEO of AirAdvisor, said: “Passengers are increasingly willing to accept fewer extras on board, but they are far less forgiving when it comes to delays, cancellations, and poor communication. Our data shows that reliability failures have a far greater impact on passenger satisfaction than ticket price alone.”

He added: “Many travelers assume that paying more automatically means a smoother journey, but the data does not support that assumption. While ultra-low-cost carriers dominate the bottom of the ranking, several full-service airlines also perform poorly because operational reliability and service consistency have not kept pace with rising fares.”

Radchenko also noted: “With safety standards now largely aligned across Europe, airlines are increasingly judged on how effectively they manage disruption. Clear communication, fast rebooking, and responsive customer support are becoming decisive factors for passengers.”

According to AirAdvisor, passengers flying with airlines ranked among Europe’s worst performers face a higher likelihood of delays and cancellations, lower service quality, weaker communication during disruption, and a greater need to rely on EU261 passenger rights for compensation and care.

The report concludes that airline performance metrics are becoming an increasingly important consideration for passengers, alongside price, when planning air travel within Europe.
