We do it simply for passenger comfort. At night, it is much easier to look outside without the glare of cabin lights on the window. I beleive that it makes for a more enjoyable night flight for the people looking outside. Those that need to work or read should have plenty of light from the reading lights.

DL_Mech: is that an empty flight? During the transition from Kai Tak to Chek Lap Kok (Hong Kong's old and new airports), all flights which flew from the old airport to the new one had its lights all on.

Eg777ER is right, the reason why they dim the cabin lights at night is for safety reasons. In the event of a failed take-off at night and the lights go out, the eyes of passengers would already have been accustomed to the darkness. If you think about it, it might significantly reduce a stampede and panic as people try to grope around in the dark if the lights suddenly went out and they're eyes aren't accustomed.

now i know, i thought i was the only one around here wondering the same question.
But i tried to work it out for myself.
I thought it would have been so that the plane can have its full power on take-off....anyway, i guess im wrong

God, to think a "mundane" topic like this could generate so much interest and confusion! Cabin lights are dimmed, so that in case of an emergency evacuation after a crash landing passengers and crew can see better as they are already used to the darkness. I would assume cabin lights are also dimmed (to answer the question regarding day flights) is that it eliminates as many potential ignition sources should a forced landing be carried out. I do know that it is NOT done so people can have a good view!! Re. individual reading lights-I have no idea. It could be that the airlines don't whant to come accrosss as completely paranoid, or when some old lady asks a F/A "where is the reading light, dear," that the reply does not put the poor thing into cardiac arrest. Passengers don't care to hear about possible crash landings-it's bad PR!!!

I was recently on several Qantas night flights, both international and domestic, and the lights were not dimmed on any of them. I was wishing they would dim them, because a night approach into a large city is more spectacular when the lights are dimmed, but they didn't.

I was on a First Air flight from Yellowknife to Edmonton on a 737-200 Combi in the early morning. The winter mornings are dark, very dark, the FA told us that it was standard night take off/landing procedures required by law. Apparently for pax safety, evacuation precautions and so the pilots can see better, dont ask me about the last reason, I dont see how it would affect it to much.
If its a night flight they tend to keep the lights off, if its an early morning flight they will turn them back on once at cruise altitude.
