The Oneworld Explorer Validator shows the following as valid (as expected)
LHR-NRT-ROR-NRT-GUM-NRT-SYD-JFK-LHR
But it does show each flight as intercontinental

Thanks - ROR & GUM are included in the south west pacific zone in MM - so should they be Asia? According to the OW
rules, both Asia and SWP are part of TC3 zone.
The way that MM calculates the validity of flights (e.g. NRT-ROR) within OW is independent of which continent (e.g. Asia or SWP) it thinks they are located in.
