Any comments on this itinerary would be appreciated. This is for work travel so it's not optimised for distance/points - but still earns well by my standards.

Following some recent posts, the LHR taxes are quite high, but as I am only transitting will these be levied?

QF allowed me to put a booking into the system, and quoted AUD$700 taxes which seemed OK. I had expected more. First sector is dated - everything else is open dated at this stage.

Comments on ticketing/payment would also be appreciated. My understanding is that the itinerary is sent to QF's office in MNL, and I arrange payment to them, then I plan to pick up the ticket in person about 5 days prior to departure.

This is my first DONE4. I have read the oneworld posts for a few months now, but I'll bet there's something I have overlooked...
