Following the recent thread re Vegan meals on Qatar I thought this statement from Qantas was interesting:
<<On flights to and from Dubai and Jakarta, Qantas does not serve meals that contain alcohol or pork.>>
Observing that both QF flights to/from Dubai go on to London it would appear that you will have to go all the way without bacon. Surely, if Moslem meals are available as a SPML it is going a bit over the top to make the entire flight pork free. To quote a letter from today's Australian newspaper - "the last time I looked QF was an Australian airline".
