For me either Quantas or Malev. I flew Malev for the first time recently, and even in pauper class (I'm cheap, I wanted to save more money for my Spit project) they serve good food and decent wine to everyone

QANTAS Ozzy, QANTAS ( i know a u should follow a q but it is an acronym. I think it stands for Queensland and Northern Territory Airline Service? ? ? Can anyone enlighten this?)
My favourite would have to be Virgin Blue. They have cheap fairs, the staff are very friendly (flight attendants are not tooo bad at all

) and its great because you pay for your food on the plane, you don't wanna eat, you don't pay, it isnt even included in your ticket cost.
