United Airlines has announced plans to retrofit its entire Boeing 737 MAX fleet with new cabin lighting systems designed to reduce passenger fatigue on longer routes.
The LED-based system adjusts color temperature throughout the flight, mimicking natural daylight patterns to help passengers adjust to destination time zones.
Implementation Timeline
Installation begins next month on domestic routes, with international aircraft receiving upgrades by mid-year. The retrofit takes approximately four hours per aircraft during scheduled maintenance.
Similar systems have shown measurable improvements in passenger comfort scores on competing carriers.
