Flew to Brisbane with them 2 years ago for xmas. No real problems, but packed to Abu Dhabi (or whichever of those places it refuels at), then about 50% full, so plenty of room to stretch out, some lucky ******s even managed to get a row of 4 in the middle to stretch out on.
No delays to the flight, food OK, dry but you can take your own on (wine box remnants are ideal).
In summary, a flight like any other, no better or worse than Gulf Air, Malaysian, Garuda or any other cheap long haul carrier.
