I'm looking at booking an AA award flight from Christchurch to LAX via Sydney and have never flown that route, so I'm a bit worried about how much connecting time to allow. The only option I see is about 90 minutes. A Qantas agent assured me over the phone that would be enough time but also said I would have to go through immigration in Sydney, collect my baggage, go through customs, and then check-in for the AA-operated flight from Sydney to LAX. That sounds like a lot to do with only 90 minutes connection time. If anyone has advice on the feasibility of that option, I would love to hear it!
