To let adults travel in peace, Malaysia Airlines will not allow children under 12 to sit in the upper deck economy-class cabin of its A380 aircraft, unless there is overwhelming demand for it. (See this post on its Facebook page.) The airline’s first A380 service will be nonstop from Kuala Lumpur to London, scheduled to start July 1. A second non-stop service to London will be added on August 25. Last year the airline announced it won’t allow infants in the first-class cabins of the A380. The airline has placed an initial order of six A380s.
