Upgrade to First Class

When I travel by air, I'm used to flying "economy" or (the etymologically ambiguos term) "coach" as many call it.
But it's good to know that if I wanted to upgrade to First Class, all I have to do is keel over dead. What?

A woman died on a British Airway flight and was moved from economy to first class...

The first-class passenger, Paul Trinder, told the Sunday Times newspaper that he was sleeping during a February flight from India and woke up when the crew placed the dead woman in an empty seat near him.
"I didn't have a clue what was going on. The stewards just plonked the body down without saying a thing. I remember looking at this frail, sparrow-like woman and thinking she was very ill," the newspaper quoted Trinder as saying. "When I asked what was going on, I was shocked to hear she was dead."

This is so weird to me. It never occured to me that people die in their sleep all the time and since a majority of airplane passengers spend some amount of time sleeping on their flights, someone's bound to cash in their ticket - so to speak - in midair.

British Airways said in a statement that about 10 passengers die each year in flight and that while each situation is dealt with on an individual basis, safety is paramount.

Crazy.
