4. Pillows are no-no!
They are never clean! Most likely, the pillow you try to sleep on was used by a lot of others before you. And what are the chances of being fully cleaned? I’d say a percentage of 10%. I remember that a friend of mine once heard a stewardess say that nobody changes the pillowcases or washes them. Yikes!
Next time you have a flight that lasts the whole night, you better bring your own pillow! It’s much safer, plus you can find plenty on Amazon at very good prices. I bought mine from here, and I have to say that I am pretty satisfied with its quality.
