Ever had trouble sleeping on a flight because of someone else's crying baby? If so, you can sympathize with the first-class passengers whose complaints have convinced British Airways, Emirates and other carriers to consider child-free seating areas.

Until recently, no airline was willing to incur parents' wrath with such a move. Now Malaysian Airlines has banned children from the first-class cabin on its Boeing 747-400 and soon-to-be-introduced A380 jets.

Travelers with babies will have to sit in economy or business class, which will be equipped with cradles.

Malaysian Airlines has taken a bold step to pamper its high-paying fliers. Other airlines with probably follow suit.
