I’ve noticed on flights when people are told to turn off their electronic devices, they just turn off the screens. Many (that I’ve seen) don’t even put the device into flight mode. So why do airlines still ask this?
There’s no real difference between an electronic device with the screen on or off, except that it’s not displaying information. Yes, the device is doing less with the screen off but it can still transmit/receive data, and airlines don’t enforce that devices are actually off.
People are still allowed to read paper books during takeoff/landing, so what is the real reason?
