I have recently taken a San Francisco - London (10 hour) flight, with a toddler in the seat directly behind me. His parents were really proactive in helping keep the child entertained in order not to disturb other passengers. However, that meant that they were reading out loud to him throughout the flight.
One might think that I'd be tolerant to people talking on a flight. One would be very, very wrong.
What specific steps can I take in all of my future flights to mitigate noise disturbance so that this experience will never, ever repeat itself?
