IndiGo, a budget airline based in India, has added designated "Quiet Zones" to its flights, banning children under 12 from sitting in rows 1 to 4 and 11 to 14. (As on most airlines, kids are also excluded from exit rows.)
The idea is to provide a little calm for customers traveling sans rug rats—though let's be honest: any squalling infant worth his formula has the lung capacity to belt past a piddling four rows of seats.
IndiGo isn't the first carrier to introduce kid-free areas. Malaysian Airlines, AirAsia, and Singapore's Scoot all have them as well.
