Thanks Amy. I had pretty much decided against Jet* anyway because by the time I had added all the extras (that you must have when you travel with kids lol) it cost pretty much the same as all the other flights and I don't see the point of paying full price to fly with a budget carrier.
The only other reason I liked them was the direct flights but they have a stop at the Gold Coast from our place and the Coolangatta airport isn't the nicest place to stop for a couple of hours.

Thanks for your help. I get a bit anxious booking flights and dilly dally for days. It drives DH nuts that I can't just make up my mind.

What company do you work for? Is it one of the big ones?
