Thank you both, it is not on 1 ticket, they're separate 1-way tickets. One is with Qantas the other Jetstar, booked directly with the airlines not together.

I did fully pay for the fares with my U.S. Citi Prestige card, but I've read different results from missing a flight due a delay (connecting same ticket or separate booking, seems hit or miss in claim approval). And they recently changed coverage from 3hr delay to 6 hour delay. We're traveling with an older parent (70s) and 3 young kids.

Thanks again, it sounds like unless there's a drastic delay we should be fine.
