Scoot Airlines, a subsidiary of Singapore Airlines, announced that it will let passengers pay about $14 to sit in a "child-free" zone. Children under the age of 12 are banned from sitting in this "Scoot in Silence" area, which will span rows 21 to 25 on its flights. This area also offers a few inches of more legroom. Scoot offers flights to Singapore, Sydney, the Gold Coast, Seoul and Nanjing. The airline joins Air Asia X, which also offers child-free zones. Air Asia X launched its "quiet zone" in February. Children under 12 aren't allowed to sit in this zone, which is composed of rows 7 - 14 in the premium cabin on some of its flights to Australia, China, Taiwan, Japan, Nepal and Korea.
