This study was carried out in Turkey on two flight routes, Boeing 737-800 and Airbus A320-200neo aircraft. In-cabin air quality was measured during the flights. Systems designed to provide fresh air for passengers and crew cause rapid deterioration of in-cabin air quality, even though travel time is shorter than other modes of transportation. In a short time, the CO2 produced by the breathing of the passengers and crew can be dispersed throughout the cabin. As a result of the measurements, it was determined that the amount of CO2 was a minimum of 748 ppm, a maximum of 3000 ppm, and an average of 1399 ppm. In addition, the relationship between temperature and CO2 was statistically examined. These results indicate that indoor air quality may be low. Decreased in-cabin air quality can cause headaches, distraction, and fatigue for passengers and employees. The distraction that may occur, especially for pilots, can lead to highly critical consequences. Therefore, monitoring of in-cabin air quality is critical. Similar studies have been carried out in Europe and America, but this is the first study conducted for different airline companies in Turkey. As a result, the aviation industry must work to develop new technologies and methods to provide better in-cabin air quality.
