There are no non-stop scheduled flights between any two antipodal locations by commercial airline service-or anything even close.
A hypothetically perfect antipode flight would be Tangier Ibn Battouta Airport, Morocco (IATA: TNG) to Whangarei Aerodrome, New Zealand (IATA: WRE), whose designated locators are 10799nmi apart,[REF] one nautical mile short of the maximum of 10800nmi, but their actual runways cross in projection.
