As far as I can gather, before an airline is allowed to operate into a country on a regular basis, most country's aviation authorities scrutinize the airline's operation including the fuel policy in use. So having operated to the US and UK for 50+ years, does QF need an alternate operating into LAX, JFK or LHR ....... not if it complies with its own fuel policy which is also approved by CASA.
Hence my question Chocks, do QF actually carry an alternate for the 380? LAX for example has KONT on the other side of town, but that's pretty much it, unless you want to go to Palmdale etc, and if you have to go to KONT, there a good chance a load of others will be needing to do it as well.
Note that the airports mentioned all have close airfields which can be used as alternates, we don't have that luxury in Australia with PER being the most obvious example.
Which is why every time I operate into Perth, my employer gives us YPLM or YPAD gas....but then it is in an old tech 777
