So having been fortunate enough to try some of the more 'fabled' lounges -TG BKK F Lounge, LH FCT FRA , the CCR in LHR, the Wing in HKG and given that I will be 'ticking off' the EY DXB F Lounge when taking QF10 in F on my upcoming only trip ever (probably) to Oz, I'd love to gain access to the F Lounge in MEL or SYD.
Unfortunately my return will be ex-BNE and BNE has no F Lounge (to speak of
So my question is - is there any way to book an 'internationally-connecting' MEL-SYD QF flight which would leave from the international terminal in MEL on the way to SYD, or similarly is there any SYD-BNE (or basically anywhere on the queensland coast) flight which would leave from the SYD international terminal and allow access to the SYD F Lounge?
(alternaively is there any access to the MEL F lounge after arrival on QF10? - I assume not given the late arrival and my research to date)
My travel plans are fairly flexible, so I could make whatever 'adjustments' might be needed to make this happen, albeit as a non-QF OWE I do not think using any Jetstar flight options will work.
Thanks in advance for any guidance.
