I flew with Malaysian LHR to SYD return in September. They have a 34 inch pitch which must be the largest in Y. The food and wine were good, and although I do not really bother with the IFE what I did use was perfectly acceptable. They are to be seriously considered. In my view BA is the one to avoid, the seat pitch is of a charter standard in economy. A pity, the crews are generally good, very professional and the food and entertainment is ok. Beware of QANTAS tickets, you might end up on a BA code share and a smaller pitch than QF. Have a good trip, I envy you, I can only go down to SYD in the colder months of the southern hemisphere.
