I am having a similar issue seeking availability for SIN-MEL. I will be looking for 4 seats in the second week of the Victorian school holidays July 2026 which is not yet available yet on Velocity, but is on Krisflyer. I am looking at the currently available dates in June 2026 to get an idea of what may become available in July and seeing no regular award availability for 4 seats SIN-MEL direct, only premium award at 57k points + A$150. I can see limited regular availability via SYD or ADL for 35k or 37k points + A$208 or A$212. While that would be fine if it were just me travelling, I would rather not do that with 2 young kids in tow.
The flights I want are available now for 30,500 Krisflyer points + A$111, so I can get them now by transferring 47,275 Velocity points per seat to Krisflyer. Alternatively, I can take the risk and wait to see whether the flights I want become available on Velocity for 29,000 points plus A$150 when those dates become available in about 3 weeks time. Noting that there appear to be ample reward seats in the second week of the April school holidays on Krisflyer, I'm minded to take the risk and just hope those Krisflyer seats are still available in 3 weeks time.
One other thing, I can see 2 ordinary rewards flights on Velocity available on most SIN-MEL flights, but availability disappears when I push it to 3. If that happens for the flights I want in July, I suppose what I should do is book my wife and 1 kid through Velocity and myself and the other kid through Krisflyer.
Happy for any comments on the above.
