As usual, I'm looking for input from more knowledgeable minds than mine. Apologies in advance for my longwinded plea for assistance.
I'm currently trying to do a trial run with dummy dates for a OWA Econ itinerary on the Qantas multi city tool to get a ballpark costing for my twin sister (who barely knows how to turn a computer on) to take a trip next year. She's finally amassed enought points for a OWA Economy itinerary. She wants to be in Tokyo for a cruise in September 2025, then I thought she could come back to Sydney for a long 'stopover', before using the second half of the itinerary to fly to Europe. I am hoping she could start the trip in say, AKL or HKG, fly to Tokyo, do the cruise and spend time in Japan, then fly back to Sydney for 6 months, then fly to LHR (or FCO depending on miles), coming back through DOH/DXB, stopping in CMB for a couple of weeks in Sri Lanka before finishing in Sydney (with the miles back to her origin point included in the 35K total). A couple of the itineraries I've tried are:
AKL-HKG (CX) TRANSIT
HKG-HND (CX) STOPOVER
HKG-SYD (pref JL or may QF if necessary) STOPOVER
SYD-DOH (QR) TRANSIT
DOH-FCO (BA) STOPOVER
FCO-DOH (QR) TRANSIT
DOH-CMB (QR) STOPOVER
CMB-SYD (QR) FINISH
The above miles on GCM (inc. the miles between SYD-HKG) are just over 34k.
Starting her in HKG gives her some extra miles to get to LHR for a stopover but will cost her more for the positioning flight. I also tried starting her in Manila - AA flies direct from there to HND.
Technically there is no rule against back-tracking I think? Is my problem that she's got a SYD stopover in the middle of the first itinerary and then coming back to SYD isn't allowed before the ticket technically closes out in HKG, even if she finishes in SYD?
Also tried the following:
SYD-HND (JL) STOPOVER
HND-HKG (CX OR JL) TRANSIT
HKG-AKL (CX) STOPOVER
(return AKL-SYD flght before resuming itinerary)
AKL-KUL (MH) TRANSIT
KUL-DOH (MH or QR) TRANSIT
DOH-FCO (MH or QR) STOPOVER
FCO-DOH (MH or QR) transit
DOH-CMB (QR) STOPOVER
CMB-SYD (QR of QF) FINISH
Mileage of 34,122k.
Thought she could just get a return flight AKL-SYD for the 6 month break in the itinerary.
I had planned to book the Tokyo part of the itinerary around December this year , then just book dummy dates for the european content until those flights become available. Classic Economy tickets aren't as difficult to find as Business Class so I thought this might work?
I just keep getting the same message on the multi-city tool: Change your departure or arrival city and try again. (#9207). I've checked flight availability on OW airlines on all the flights on expertflyer. I've checked availability on the Qantas website (even though it seems not to like transiting through DOH sometimes for some reason - DXB would do as well). I must have a flaw in the itinerary because I keep getting the same message.... I can't even make the itinerary work, let alone get a ballpark costing.... I had in mind that the fees/surcharges might probably come to around the $1k mark for this econ itinerary? Am I wildly out?
I must be making some really obvious stupid error that I'm going to be very embarrassed about..
