No, it isn’t by installing a credit card reader in the lavatory or making us stand (but let’s not give them any ideas). Airlines already have charged extra for “preferred seating” as in I would prefer not to sit way in the back of the plane next to a screaming baby. Apparently, though, those seats (which I often seem to get) make it far more likely that you’ll survive. I wrote about this at work.

“Ladies and gentlemen, we are now ready for general boarding. Our diamond preferred ‘more likely to survive a crash’ passengers are welcome to come to the gate.”

You won’t be hearing an announcement like this at the airport any time soon, but it is a fact that some of the most and especially the least expensive seats on an aircraft give you better odds of living should tragedy strike. KLM India came under fire for spelling this out in a since-deleted tweet.

Discussing air travel fatalities isn’t only in bad taste but is believed to be bad for business. Or is it? U.S. airlines have found an additional source of income in recent years in charging for preferred seating—generally those that might have some extra legroom or let you deplane more quickly.

Seats at the back of the plane are therefore less likely to command a premium above the advertised fare, but perhaps they should according to KLM India’s tweet. Already-expensive ones near the front are slightly safer, but the fatality rate “is least for seats at the rear third of a plane.”
