I would need to change terminals. I figured... See, I don't know LAX at all... But I figured... I would arrive at whatever terminal... Collect my baggage... Then have to queue to get through customs. How long that took would depend on how many flights arrived around the time I'm trying to queue.

Then... I would need to get myself to the domestic terminal (I heard that it is often faster to walk than to catch a free shuttle bus and that the weather was typically fine. Though... This will be January and I have no idea on what the climate will be like... Then, once I get to the domestic terminal I'd need to Queue to check in luggage for the domestic flight. Because I'd certainly have more luggage than mere carry-on.

Also... I'm sure I'll be DYING for a cigarette about then... But I figure I need to collect my luggage and then check it in again precisely because I have an international carrier for flight in (Quantas) then an American carrier for the domestic flight (booking the flights seperately). So... 5 hours, I thought. And hope that I don't get detained with customs (since they will want to check everything out before letting me through and I've heard LAX can be a ***** with that if you are on an international passport.
