Royal Brunei Airlines
 

Can anyone tell me if I can get credit with any other airline partner for flying with Royal Brunei, from Australia to London, round trip (first class)it seems a shame to waste all those potential points....

They code share with British Midland. You might want to take a look at their site at www.bruneiair.com

It might be worth noting that Royal Brunei does not serve alcoholic beverages. So, while you won't be getting any Krug from them, you are welcome to bring your own (assuming you are not Muslim).

See their website and look under the 'Meals' section.

I have heard that before Royal Brunei flight takes off, short worship takes place inside plane.

... and most of things in 1st class are gold plated.
