Cologne/Bonn Airport has received its first-ever rating from the specialized rating organization Skytrax as part of an international quality assessment. The London-based institution awarded the Rhine-based airport its global four-star regional airport certification.
This rating was based on a multi-day assessment conducted in June 2026, during which all phases of the passenger experience were analyzed. The assessors evaluated the existing infrastructure, digital services, and the service quality of the on-site staff. Since Skytrax ratings are considered significant benchmarks for comfort and handling efficiency in the civil aviation industry, the result provides an independent assessment of the airport's current state of modernization. The assessment focused particularly on the recent structural and procedural changes at security checkpoints and in the passenger terminals.
The modernization program and the redesign of passenger processes
In connection with the assessment, the management of Cologne/Bonn Airport GmbH refers to the ongoing investment program entitled Next Chapter. This project aims to restructure processes along the entire passenger handling chain – from arrival at the terminal and baggage check-in to boarding the aircraft. The transformation encompasses four key areas: the automation of ground processes, the modernization of security checks, the upgrading of waiting areas, and the redesign of the retail, food service, and lounge offerings.
A significant part of these measures involves automating the check-in process. To reduce waiting times for travelers during peak holiday periods, investments have been made in self-service infrastructure. Passengers now have access to 20 self-tagging kiosks and 16 automated baggage drop-off counters. These systems are slated for further expansion in the near future. Critical industry observers point out that while increased automation can boost efficiency, IT malfunctions or user errors by inexperienced passengers could create new bottlenecks at the machines, which would then have to be addressed by the remaining staff.
Technical innovations at the central security checkpoint
A key focus of the Skytrax audit was the evaluation of the newly designed central security checkpoint. By the start of the 2026 summer holidays, all security lanes were equipped with state-of-the-art computed tomography technology. These CT scanners allow security personnel to analyze three-dimensional images of hand luggage, enabling passengers to leave electronic devices and liquid containers with a volume of up to two liters in their luggage during the screening process.
The auditing firm highlighted the bright and spacious design of this area, as well as the clear wayfinding system, in its report. From a business perspective, the procurement and maintenance of these complex CT systems represents a significant financial burden for the airport operator. While the technology increases passenger throughput per hour, the long-term reliability of the systems under full load during peak travel times still needs to be proven in continuous, ongoing operation.
Quality of stay in Terminal 2 and revision of the commercial offering
In addition to the security checks, the design of the waiting areas in Terminal 2 has been improved. The newly created seating areas follow a regional theme, inspired by the course of the Rhine River. The concept includes an open layout, the integration of plants, and the installation of more power outlets for mobile devices. Skytrax auditors assessed these measures as beneficial to the overall travel experience.
In parallel, the commercial sector at the airport underwent restructuring. In cooperation with catering partner Autogrill, 18 cafes and restaurants were renovated to reflect the changing consumption habits of passengers. This development is complemented by modernized duty-free zones and the introduction of a redesigned lounge concept. Improving the overall experience in the terminals aims, among other things, to increase the amount of time passengers spend in the commercial areas and thus stabilize the airport's non-aviation revenue. Critics point out that such modernizations must be repeated regularly to remain competitive with neighboring major airports like Düsseldorf or Frankfurt.
Background on the rating organization and outlook
Skytrax, the organization responsible for the rating, was founded in 1989 and has operated the World Airport Rating program since 1999. The system ranks airports worldwide on a scale of one to five stars, taking into account both the physical product quality and the service provided by staff. Achieving four stars places Cologne/Bonn Airport in a segment of commercial airports that demonstrate a good standard in the core areas of passenger handling.
For the airport's management, the result confirms the value of previous investments, but also raises the question of how to maintain the achieved level of service in light of fluctuating passenger numbers and rising operating costs. Maintaining the four-star status requires ongoing expenditure on infrastructure maintenance and staff training. The coming years will show whether the implemented process automation and new control technologies are sufficient to consistently meet the quality standards of international auditors, even in future re-audits.
