My husband and I are looking to fly CBR-DPS in Aug 2022 (or if that doesn't work, Mar 23). We go there not infrequently, and usually manage to get a classic reward ticket for business class - always on Jetstar. Looking at both August and March, there are no business class award flights available. Can anyone comment on whether they are likely to become available? Or would we be better to book an economy ticket for cash and try to upgrade? Have never attempted an upgrade and it seems a bit uncertain - are there any tricks to increasing the likelihood of getting an upgrade? We are newbies at this game - only FF Bronze. We have a fair few points through business, but not enough to burn for a non-classic award. Any help welcome!
