First investigation
- using the online tool (rtw.oneworld.com)
- very simple LONE4 starting and ending in SYD (SYD-HKG-LHR-LAX-SYD)
- QF or CX for SYD-HKG, CX or BA for HKG-LHR, BA or AA for LHR-LAX, QF for LAX-SYD (could not get the tool to show the AA codeshare for this last segment)
- all, of course, had the same base fare (AUD3906, which is AUD7 more than the published fare, because of HKG's little nuisance tax which it requires be added to the base fare rather than be separately listed)
* so I looked only at the total of taxes and surcharges
- these varied between AUD968.44 and AUD1349.54 depending on the mix of airlines used
- cheapest was CX-CX-AA-QF; most expensive was QF-BA-AA-QF
I will add the second investigation shortly (it will navigate through the qantas.com web site to the tool in order to see if there is any difference)
Edited to add:
Second investigation
- Starting at Qantas.com.au and clicking on its Round the World link, which takes me to the online tool at rtw.oneworld.com but with Qantas branding instead of Oneworld branding (the url is https://rtw.oneworld.com/rtw/?origin=QF)
- Enter the same itinerary as before (specifying CX as the first carrier)
- Get the same pricing as before
- Click on Proceed to Booking
- AND THE PRICE INCREASES
- looking at the list of taxes and charges, there is an additional line of "Multiple Carrier Surcharges/Fees" totalling AUD 297.70
Mmmm
