A new Airbus plane significantly diminishes the impact of jetlag through a combination of a humidification system, onboard fresh air and an adaptable color temperature system, which can produce different light color combinations dependent on the flight length and time zone changes. The LED lights simulate the natural phases of the day during the flight, encouraging passengers’ body clocks to adjust gently during the flight. The Airbus A350 XWB is currently only being used on select luxury flights by Qatar Airlines and Singapore Airlines.
