I'm looking to buy a LONE4 in the UK to take the family round the world next year. We spoke to Trailfinders initially, but they mentioned today that they charge 125GBP fee per ticket. That's 500GBP for the whole family. Gulp.

First stop was the online tool, but I've had some issues with it. The planning mode tells me there are the flights I want AKL-SCL, but in the booking mode it won't show them. Could this be because it is for Aug 2010?

If the online tool lets me down, what's the best way to book this? Should I phone one of the airlines to book it? If so which one? My itinerary includes AY, JL, CX, QF, LA, BA if that makes any difference.

Thanks!
