With rising travel demand, some foreign airlines now sell 'Quiet Zones'—designated economy areas that restrict young children to offer a calmer cabin. Singapore’s Scoot markets a “Scoot-in-Silence” forward section banning passengers under 12; AirAsia X limits its Quiet Zone to flyers aged 10 and older; Indigo also blocks children under 12 in certain rows. Japan Airlines takes a different approach by displaying a baby icon on seat maps when an infant (8 days–2 years) is booked nearby so other passengers can choose quieter seats. Quiet Zones cost a modest premium (roughly KRW 40,000–60,000) and are promoted as cost-effective alternatives to business class. South Korean carriers have not adopted explicit 'no-kids' zones—likely wary of criticism about child discrimination—but emergency-exit seats (restricted to those 15 and older) often serve as a de facto quiet option. The trend reflects demand from solo and light-sleeping travelers willing to pay for peace on board.
