It can be cold, a baby can scream for what seems like hours and the food can be inedible. But one guaranteed joy of flying a fairly long distance is the chance it gives you to read.
As the hours stretch out before you the chance to lose yourself in a book without the worry that the phone or internet will distract you is something rather wonderful.
These days it's very rare for me to fly but when it happens I pack the books and enjoy every second of the reading time.
