Every traveler has their pet peeves, but crying babies are almost guaranteed to grate.
Now Japan Airlines has revealed a new tool that lets you dodge infants when you book your seat.
"Passengers traveling with children between 8 days and 2 years old who select their seats on the JAL website will have a child icon displayed on their seats on the seat selection screen," reads the airline's website.
The move will be a boon for travelers who like to avoid babies.
"This lets other passengers know a child may be sitting there."
And one Twitter user praised the feature following a recent flight.
"Thank you, @JAL_Official_jp for warnings me about where babies plan to scream and yell during a 13 hour trip," wrote Rahat Ahmed.
"This really ought to be mandatory across the board."
Before babyphobes get too excited, Japan Airlines cautions that the baby map will not display child icons in certain situations.
It only works for bookings made through the JAL website, for example, and icons will not display if there is a change in aircraft.
If you are taking a small child on your trip, JAL offers a number of services to make your experience better.
The airline provides a number of strollers for rent in the airport, and will accept baby strollers as checked baggage for free.
Passengers traveling with infants also enjoy priority boarding, and offers hot water for bottles as well as diaper changing facilities on board.
