Why do we HAVE to pull down the blinds?
I was recently on a daytime flight from BKK to LHR. About 90 mins into the flight, after the meal service, the FAs came round and told us to pull our window blinds down.
Is this normal on a day flight? I understand it's the right thing to do on a night flight so that people can watch a movie and/or sleep, but - purely selfishly - it meant I couldn't see places we flew over and debated whether it was helpful in reducing jet-lag or not?
I've only ever flown from south-east Asia once before, and that was overnight, so I was wondering if this is normal practice, or airline practice?
Cheers
