It is known that most airlines in the world disallows passengers to drink alcoholic drinks brought by them on board, and they can only drink alocholic drinks served by flight attendants. This is to prevent passengers drinking excessive alcoholic drinks & then makes some action dangerous to passengers.

But Royal Brunei Airline is very unique. It does not serve any alcohlic drinks on board, and passengers are allowed to bring alcoholic drinks of their own, the only one in the world, and is opposite of other airlines!

Even other flag carriers of most Muslim countries, like Saudi Arabia & Malaysia, have alcoholic drinks served on board.
