ConcordeBoy is right about AKL
. If you fly a direct route from AKL
you'll pass just N of the point that is 1200 nm from Hilo and LAX
. So even if 180 minutes is a bit less than 1200 nm, the route is "fairly straight".
As for what routes a twin will never fly: depends on what alternates continue to exist. Will Ascension always be available? How about Easter Island? Is Wake endangered? But yeah, the South Pacific route (AKL
now; there's never been a SYD
nonstop has there?) will likely be the last to go ETOPS.
