And alas, we get to this problem: AA7358 HNL-SYD doesn't have availability in L on 9/25. QF 4, on the other hand, does. I doubt the rate desk will be happy about pricing this out if the AA over-the-water is waitlist.

If I really wanted to I'd imagine I could find another date where AA7358 does have L, book that, price and ticket, then change back to QF4 on the date that I want... at this point, probably easier to pick up the phone!
