Only been once and it was with BA/Qantas as we were doing a few internal flights around Australia and got a good package that way. Bloody economy class though, not fun at my height and with my legs especially when the plane "breaks" whilst at the gate at Heathrow leaving us onboard for 3.5hrs, no aircon, without moving, before even getting into the first leg of the journey via Singapore...
I've been told Emirates is the best option for economy class - reliabily by a mate who's sister lives in NZ.
