More realistically, child fares presumably earn full miles. Treating an 11 year old nephew to serious travel became a lot more enticing...
But child fares are generally 75% (vs. 10% for infant fare). Also aren't child fares limited (the lowest deep-discount adult fare isn't eligible, so child fare is often more than the cheapest adult fare, at least on some airlines).
