Hello all, I've been lurking at these forums for a little while but with a RTW holiday in the works for September I thought I'd break the ice and request your thoughts on my prospective itinerary.

I'm coming off a very low base on QFF and therefore maximising the miles and SCs on offer would be nice. But at the same time, this is a holiday rather than a mileage run and I would like to both sample each of OW's "Big Four" and also spend some time in all of my stopover cities! Therefore it's mainly the carriers I'd like some guidance with as opposed to the actual route.

Considering I'm operating off the wages of a humble clerk and am paying for this myself, I've opted for a 26000 Global Explorer in Economy with a route as follows:

PER-HKG (CX)
HKG-LHR (BA)
LHR-JFK (AA)
JFK-LAX (AA)
LAX-SYD-PER (QF)

I'm well aware that flying AA in L class gives you absolutely nothing on the QFF, but there aren't any codeshares I can find that could remedy this.

Is CX preferable for HKG-LHR? I would like to upgrade to WTP on that sector because I have a feeling I'll need the extra room to help me sleep, but if CX Economy is tolerable I'd certainly consider using the WTP on the transatlantic sector instead.

Any guidance which the wise heads here would be able to give me would be handy to have in the weeks leading up to my booking. I'm certainly not looking to stack up on points at the expense of a sane holiday, but if there are better solutions you can think of I'd like to consider them.
