...flying Jetstar doesn't give you that.
Look at Melbourne. You walk past all the nice Qantas gates down to the dungeon to the dirty lounge where the floor looks like it's never cleaned and the seats are covered in stains.
And the air is humid, sweaty and rank, as if the air conditioning isn't working, and the legionnaire's haven't been around to clean up for a while. It's like walking into a giant teenager's sneaker.
