my personal choice is that I wouldn't fly tiger with my kids only because of all the horror stories I've heard & seen on that show airways!
If it was me flying alone (or with another adult) I would possibly fly tiger if it was a large price difference, like maybe saving over $30 EACH way???
My preference is always virgin blue. I love them & they're usuallt cheap anyway. I've flown jetstar a couple of times, cant really complain. I haven't flown qantas for YEARS only because I always book virgin, they're usually alot cheaper than qantas.

Is it a large saving hun??

Sorry I wasn't really any help at all!!!
