Globalizer,

I expect the companies to make and follow their policy. No doubt the cabin crew knows what they're doing, but I have flown into the same airport on the same airline on equally uneventful clear days and have had to shut down at different times. This eats into my productivity and I do plan to hold people/companies accountable to their own policies. That being said, my complaining would be in the form of a letter to the airline each time this happens and not a direct complaint to the cabin crew. The 10k limit when you take off is always enforced clearly. Once you hit 10k feet, you can use any electronic device. The same is not being done for the descent part.
