Aussies love to travel. If they don’t want to go to/via Asia they may want to go to/via the US.
I just booked SYD-LHR via Rio outbound and HNL inbound. Motivated by price (7K all in business) and DSC, but also relieved to know I don’t have to worry about SIN or Asia in case the situation continues to get worse.
Doesn't always necessarily mean a full plane on a widebody will guarantee profit either.
If specific routes are mostly of the low yielding/VFR traffic, it's basically a recipe for QF to throw money down the toilet.
