Erm, I use Ear Planes on flights and like f*** am I taking those out to be polite. Why would I want to ruin the first few hours of landing with weird spacey hearing, popping in my ears and minor pain
I'm perfectly capable of responding to a question even though they are in
Also, there are a lot of people on flights who really don't like flying and listening to music and ignoring what is going on around them is their way of coping, not sure why it's such an issue for other people to criticise their coping techniques.
