Qantas are having a Business class sale.
Brisbane to LA is $3394 return. Dates I used are January 15th 2020, return on Feb 13th.
Other destinations and cities are also on sale, so I would take a look if interested.
- Minimum 10 day stay
- Maximum 12 month stay
- 1 free stopover ($100, pp for additional)
- Cancellation fee $600
There is no landing page that I can find for this sale, so just start searching.
Also the deals don't appear to be available from third parties. Must use Qantas's website.
