Air Tahiti Nui is the flag carrier of the French overseas collectivity of French Polynesia, with its head office in Papeete, Tahiti. It operates long-haul flights from its home base at Faa'a International Airport, with a fleet consisting of four Boeing 787 Dreamliners.
Air Tahiti Nui Flight 64 (TN64/THT64) was the world's longest domestic flight ever. The flight, operated by Air Tahiti Nui, was between Papeete in French Polynesia and Paris in metropolitan France, traversing a distance of 15,715 kilometers and taking 16 hours, 20 minutes. It is considered a domestic flight as French Polynesia forms an integral part of the French Republic.
Air Tahiti Nui began the route on 15 March 2020, departing Faa'a International Airport at 3:14 am local time as flight TN64, flying nonstop to Charles de Gaulle Airport, and landing at 6:00 am local time on 16 March, taking 15 hours and 46 minutes. The Boeing 787-9 operating the flight (registered F-OTOA) was only partially filled with passengers.
The non-stop routes flown by certain airlines were developed as consequence of the COVID-19 pandemic and the subsequent restrictions imposed by the United States over international flights which came into effect on 11 March 2020. Before the pandemic, the flight between Papeete and Charles de Gaulle Airport in Paris was operated by Air Tahiti Nui as well as Air France with an intermediate stop at Los Angeles International Airport, while the flight between Papeete and Orly Airport in Paris was operated by French Bee with an intermediate stop at San Francisco International Airport.
