Editing Antipodes (section)

=== Future theoretical antipodal routes ===
A hypothetically almost perfect antipodal flight would be [[Tangier Ibn Battouta Airport]], [[Morocco]] ([[IATA]]: TNG), to [[Whangarei Aerodrome]], [[New Zealand]] (IATA: WRE), whose designated locators are {{convert|10800|nmi|mi km|sigfig=5}}<!-- EACH TO 5-DIGIT PRECISION --> apart,<ref>[http://www.gcmap.com/mapui?P=tng-wre%0D%0A&R=&PM_q=%2A&PM=%2A&MS=wls&MP=&MC=&PC=red&PW=&PT=&RC=navy&RW=&RS=&DU=nm&DM=&SG=&SU=kts&EV=&EU=kts Great Circle Mapper] Access date: 2017-09-24,</ref> almost the maximum possible distance. However, with only a length of {{Convert|3599|ft||abbr=on}}, Whangarei's runway is too short to accommodate any current ({{as of|2015|lc=y}}) commercial jet airliner, especially one with the required range. Traveling between them would currently need at least two plane changes.

Other near-antipodal major city pairs include:{{citation needed|date=August 2023}}
* [[Hamilton, Bermuda]] and [[Perth]]: {{Convert|19,966|km||abbr=on}} apart
* [[Taipei]] and [[Asunción]]: {{Convert|19,912|km||abbr=on}} apart
* [[Santiago]] and [[Xi'an]]: {{Convert|19,897|km||abbr=on}} apart
* [[Madrid]] and [[Wellington]]: {{Convert|19,876|km||abbr=on}} apart
* [[Tangier]] and [[Auckland]]: {{Convert|19,859|km||abbr=on}} apart
* [[Jakarta]] and [[Bogotá]]: {{Convert|19,808|km||abbr=on}} apart
* [[Quito]] and [[Kuala Lumpur]]: {{convert|19,700|km||abbr=on}} apart

The ambiguous airport designation [[HLA (disambiguation)|HLA]] could refer to either '''[[Lanseria International Airport]]''' ([[IATA airport code|IATA]]: '''HLA''', [[ICAO airport code|ICAO]]: '''FALA''', 25°56′S 027°55′E) in South Africa or '''[[Huslia Airport]]''' ([[IATA airport code|IATA]]: '''HSL''', [[ICAO airport code|ICAO]]: '''PAHL''', [[Federal Aviation Administration|FAA]] [[Location identifier|LID]]: '''HLA,'''  65°42′N 156°21′W) in Alaska.  While these airports are not quite antipodal (only {{Convert|15,581|km|mi nmi||abbr=on}} apart), they are notable considering that they share the same designation. Automated systems that select the wrong airport from a database could lead to navigation errors or large outliers in data analysis.
