I’ll be honest, whenever all of the lights are turned off on a flight, my first thought is: “Awwww! Cosy!” because, as a treasured traveller, I figured that creating a snug atmosphere was just a nice thing that airline staff did.
Hilarious in retrospect.
As with most if not all things on flights, it comes down to the safety of passengers and staff. Not to improve the vibe or make sleeping on the flight easier though I will admit that these are lovely bonuses for me at least.
Why are the lights dimmed on flights?
