Flights linking major airports such as New York John F. Kennedy International Airport (JFK) and Hong Kong International Airport (HKG), London Heathrow Airport (LHR) and Tokyo Haneda Airport (HND), or Chicago O'Hare International Airport (ORD) and Beijing Capital International Airport (PEK) often find that a transarctic route. Routes such as Newark Liberty International Airport (EWR) to Hong Kong International Airport (HKG) and Toronto Pearson International Airport (YYZ) to Shanghai Pudong International Airport (PVG) rely on polar shortcuts to remain competitive in both cost and schedule. While conditions at these airports can be challenging, they provide essential safety coverage for polar routes. For commercial airlines, these environmental risks represent unacceptable uncertainties when compared with established Arctic routes. The accident ended Air New Zealand’s Antarctic sightseeing flights and highlighted the unique risks of Antarctic aviation.
