Turkish leisure airline Mavi Gök Airlines has changed aircraft on its daily service between Cologne/Bonn Airport and Antalya. Since the summer 2026 flight schedule, the airline has been operating the route with a Boeing 777-300ER, replacing the previously used, smaller Boeing 757.
The use of the twin-engine wide-body aircraft increases the capacity offered on the route by 22 percent to a total of 339 seats per flight. The service, offered as part of the seasonal scheduled and charter flights which continue until November, is heavily dependent on demand from major tour operators, who also market the integrated premium classes.
The switch to this type of long-haul aircraft for European short- and medium-haul routes reflects a common practice among airlines responding to the high volume of flights during the summer holiday season. Cologne/Bonn Airport sees over 200 weekly departures to Turkey during the summer months, with Antalya being a key destination, offering up to 13 daily connections. Mavi Gök Airlines, founded in 2007 as a maintenance company and licensed as an airline in 2022, is utilizing the increased seating capacity to maximize slot efficiency at the highly regulated airports of Western Europe. The company has been a member of the International Air Transport Association (IATA) since 2024 and holds the corresponding IOSA safety certification.
Aviation experts also consider the use of wide-body aircraft like the Boeing 777 on relatively short routes from a critical economic perspective. Aircraft of this size are optimized for long-haul intercontinental flights and, for shorter flight times, have comparatively higher operating costs because the takeoff and landing cycles put more strain on the aircraft. Furthermore, handling an aircraft with more than 300 passengers at the terminals requires tight logistics from ground services to meet the short turnaround times calculated for the low-cost and leisure travel segment. Delays in boarding or baggage claim can quickly lead to consequential delays in the daily flight schedule in the congested European airspace.
The airline's decision underscores the intense competition in the Turkish charter market, which is largely dominated by joint ventures like SunExpress and operators such as Pegasus Airlines. While the provision of larger capacities by niche providers offers regional and secondary airports like Cologne/Bonn a stabilization of passenger numbers, it simultaneously increases their dependence on seasonal tourism effects. Whether the daily occupancy of a Boeing 777 on this route can be made economically viable throughout the summer months depends on the continued willingness of package holidaymakers to book.
