The secret code used by airline staff when a passenger has died

Over 20 million people have a fear of flying

• Airline staff use the code to avoid alarming other passengers
• About eight million people fly every day. On planes, that is.

This year, The International Air Transport Association (IATA) estimates that four billion travellers will use air travel.

All this means that passenger deaths while 30,000ft (or higher) up is an inevitablity. It's far from ideal, but airlines must have procedures in place to deal with such incidents.
