interesting fact for those with children (or those trying to be as far away as possible from them on a flight): MH has a "kids free" zone in Y on the upper deck of their A380s. No children under 12 allowed up there. This is in addition to their long-standing 'no kids in first class' policy.
Advance seat reservations in Y on MH generally have fees attached to them, no status-based exceptions at all. Even Enrich Platinum members have to pay.
