Fraport Greece celebrated another successful season at Chania Airport, with management reporting passenger satisfaction of 4.46 out of 5. The Crete Aviation Observatory (CAO), represented at the event, brings an additional data-driven perspective through ongoing research into airport performance and sustainability.

Chania International Airport (CHQ) is expected to record passenger traffic growth exceeding 8% in 2026, according to projections shared by airport management (Tassos Tiniakos) during a Fraport Greece event held on November 1 to mark the conclusion of the peak tourism season.

The airport also reported a passenger satisfaction score of 4.46 out of 5, pointing to a strong assessment of service quality during a period of sustained demand.

The figures highlight two increasingly important dimensions of airport management: accommodating passenger growth while maintaining service standards.

For tourism-dependent regional airports, where seasonal fluctuations place considerable pressure on infrastructure and operations, the relationship between traffic expansion and service quality is particularly significant.

Beyond Traffic Growth: Measuring Airport Performance

Passenger volumes remain a central indicator of aviation market development. However, traffic growth alone provides an incomplete picture of airport performance.

Operational efficiency, infrastructure adequacy, environmental responsibility and socioeconomic contribution are increasingly relevant to assessing the long-term development of airport systems.

This broader perspective is reflected in research undertaken by Dimitris Zopounidis, founder of the Crete Aviation Observatory (CAO) and PhD candidate at the Technical University of Crete, whose doctoral research focuses on airport sustainability assessment and multicriteria performance evaluation.

Working at the Data Science Laboratory of the Technical University of Crete, D. Zopounidis has developed a research framework examining the sustainability performance of the 14 regional airports operated by Fraport Greece.

The study, titled Airport Sustainability Assessment: A PROMETHEE-Based Methodology and a Case Study for Greek Airports, was presented at the 102nd Meeting of the European Working Group on Multicriteria Decision Aiding (EWG-MCDA) in Zurich in September 2026.

The research introduces the Airport Sustainability Performance Index (ASPI), combining 13 indicators across five dimensions: environmental performance, infrastructure, accessibility, socioeconomic contribution and operational characteristics.

Using the PROMETHEE II and SMAA-2 multicriteria decision analysis methods, the framework produces comparative airport rankings while accounting for uncertainty in the relative importance of sustainability criteria.

Chania Among the Leading Airports in Sustainability Assessment

The research findings place Chania Airport among the strongest performers within Fraport Greece’s regional airport network over the 2018–2024 assessment period.

Chania ranked first among the 14 airports in both 2021 and 2022, before placing second in 2024, according to the study’s sustainability rankings.

The results are particularly relevant because the assessment extends beyond conventional traffic-based comparisons. Rather than rewarding airport size or passenger volumes alone, the methodology evaluates performance across multiple sustainability dimensions.

The findings also illustrate how airport performance can be assessed comparatively over time, identifying changes in relative position and differences between airports operating under distinct geographical, infrastructural and seasonal conditions.

Importantly, these historical sustainability rankings and the passenger satisfaction figure reported for 2026 represent separate assessments, based on different methodologies and observation periods.

CAO’s Role in Aviation Data Analysis

The Crete Aviation Observatory was represented at Fraport Greece’s end-of-season gathering, reflecting its continued engagement with the aviation sector and airport stakeholders in Crete.

Founded in 2021, CAO focuses on aviation data collection, analysis and monitoring, covering passenger traffic, airline networks, connectivity developments and the wider evolution of air transport across the island’s airports.

Its analytical work seeks to translate aviation datasets into evidence-based insights on market developments, regional connectivity and airport performance.

The Observatory’s participation also reflects the growing relevance of independent aviation research in understanding the relationship between airport operations, tourism demand and regional economic development.

For CAO, the challenge extends beyond documenting annual growth rates to identifying the structural factors shaping the long-term competitiveness and resilience of Crete’s aviation infrastructure.

The Next Phase for Chania Airport

The event brought together members of the airport community, recognising the contribution of the people and organisations involved in maintaining airport operations throughout the tourism season.

For Fraport Greece, the projected increase in passenger traffic and the reported satisfaction score provide encouraging signals as the airport prepares for the next phase of its development.

Nevertheless, sustaining growth will require continued attention to infrastructure capacity, operational efficiency, airline connectivity and environmental performance.

The wider significance of Chania’s trajectory lies in the distinction between expansion and sustainable development.

An airport’s long-term success is determined not only by the number of passengers it handles, but also by how effectively it manages resources, maintains service quality and contributes to the economy it serves.

For Chania, the combination of continued traffic growth, positive passenger feedback and strong historical sustainability rankings provides a useful starting point for assessing that longer-term trajectory.

The 2026 traffic projection and passenger satisfaction score were communicated by Chania Airport management during the Fraport Greece event. The sustainability rankings refer to independent academic research covering 2018–2024 and should not be interpreted as a current Fraport Greece or passenger satisfaction ranking.
