Japan Airlines launches seat map that helps passengers avoid babies

Japan Airlines is winning praise for displaying where babies are on planes as customers choose their seats.

A child icon appears on seats that are scheduled to be occupied by a passenger travelling with children aged under two years.

However, the Japan Airlines website notes babies booked on flights through other websites or as part of a tour won't show up in the seat booking system.

The service is being celebrated by some on social media, while others are urging people to be tolerant of travelling babies and their parents.

"Thank you Japan Airlines for warning me about where babies plan to scream and yell during a 13 hour trip. This really ought to be mandatory across the board," tweeted venture capitalist Rahat Ahmed.

"Please take note, Qatar Airways: I had three screaming babies next to me on my JFK-DOH flight two weeks ago."

One of the many replies to Ahmed was a father asking him to "chill".

"As a father of five and having travelled with each one as a baby at one point or another, I try to do everything I can to keep them from crying," said David Walker.

"It's hard on parents too. And remember: it's just one day. You'll survive your flight."

Some Twitter users suggested noise-cancelling headphones as a way to ensure peace and quiet on flights, while others talked about other types of passengers that could come with warnings, such as "loud breathers, noisy eaters and armrest hoggers".
