The travel industry is no stranger to adults-only sections of hotels, resorts, and cruise ships, but a child-free area on an airplane may raise some eyebrows.

IndiGo, an Indian budget carrier, is introducing “Quiet Zones,” areas of its aircraft where passengers ages 12 and under are forbidden. Rows 1-4 and 11-14 are off limits to the tiny fliers.

The company says the zones are for business travelers who prefer to get some work done in flight.

Today.com reports that child-free areas are not entirely unheard of: they’re found aboard some Malaysia Airlines, AirAsia X, and Scoot airplanes.
