*A matched, but their fare has templated routing so you can't go quite as far out of the way.
Just to clear up something from earlier regarding Australia:
- There is no prohibition on transfers or stopovers in SYD, but the JL fare only permits transfers in Japan/Indonesia (2 each direction) and North America ish (3 each direction in YVR/CONUS/Mexico/PR).
- The AA fare requires the stopover to be at the gatewayin Area 3, so in order to pick up the stopover, you must route via LAX-SYD (no TYO).
- But this is a mileage fare, so a stopover in SYD will get HIP checked. It's a valid construction, but you won't like the price.
- The only really plausible stopover is in Japan on the JL fare, which exempts Japan from HIP checks.
- The AA fare offers a ticketed point deduction of 2,000 for travel via DFW or LAX, which helps some of these long routings.
Fare construction with a stopover in SYD and a HIP check (INXQFVN1, JFK to SYD is the forced fare):
