Thanks guys, that was exactly the information I was looking for.

Migflanker, I was thinking the same with most families booking their long-haul trip a long way in advance. Also, most last minute business travellers tend to persuade their employer to pay for business class on such a long 15 hour flight.

At the moment its looking great with little staff booked on these flights, so fingers crossed it stays that way. I guess worst case I always have other options via AKL, SYD or BNE to get back.

Thanks again guys
