Personally, I loved EY! However since I've moved from Sydney to Perth, I can no longer fly EY (EY recently stopped flying to/from Perth.) I've now made the switch to Singapore Air, which have a much better J product.

I'm assuming Qantas?

The Phuket and Bali routes operated by Jetstar seem to occasionally have some interesting characters on board.But behaving like that onboard a flight is never acceptable.

I learnt this the hard way when I moved house in NSW. They wouldn't let me sign up to a new contract, instead they sent me over to Red Energy.I shopped around and around and found a better option with another provider. It was good while it lasted.

If the flight is from the east coast to Perth, then yes you will get a meal. Otherwise it's a pretty lame snack service.
