One strategy that may work is forcing Aeroplan to give you a J seat by coming up with stopovers that have J availability as opposed to looking for "direct" flights to BNE. This is what I did flying from LAX back to Australia where I couldn't find a single J award on the dates I wanted to travel. However, I did find J from LA to Seoul then J a couple days later from Seoul to Sydney on Asiana.
The relevant layover points for Australia for Asia-Pacific crossing are:
- Tahiti (PPT)
- Tokyo (HND/NRT)
- Seoul (ICN)
- Taipei (TPE)
- Singapore (SIN)
- Auckland (AKL)
The relevant layover points for Australia for a A&P crossing are:
From there once you stopover in your European gateway you'd then connect on a Middle East carrier like Emirates or
Etihad, or potentially an Asian carrier.
One key thing to keep in mind is the MPM (maximum permitted mile) rule: when
flying partner airlines exclusively, no routing involving a stopover can exceed more than double the miles flown compared to a nonstop routing from origin to destination. In other words 14,702 is the most you can fly with that given origin and destination. As an aside, this is precisely why origins and destinations to East coast North America are quite attractive since the MPM is close to 20,000 miles which lets you loop around to any point of the world.
Now you probably noticed I emphasized flying partner airlines exclusively. So what happens if you include a segment operated by Air Canada? Well it turns out that two things happen. First the pricing is no longer fixed to the amounts stated in the award chart but can fluctuate greatly (i.e. 400K mile awards to BNE in J on AC). Second, the routing rules aren't based on MPM anymore but instead IATA market rules (i.e. the rules you would normally get had you bought a cash ticket with Air Canada). These rules are both opaque and more importantly often ban such circuitous routings that may find these hidden "J" seats.
