World's longest domestic flight

The flight, operated by Air Tahiti Nui, was between Papeete in French Polynesia and Paris in metropolitan France, traversing a distance of 15,715 kilometres (9,765 mi; 8,485 nmi) and taking 16 hours, 26 minutes.

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.

[14][15][16][5] 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.

[18][19] The airlines serving these routes also held traffic rights to transport passengers between either Paris or Papeete and the intermediate stop.

Both the Boeing 787-9 used by Air Tahiti Nui and the Airbus A350-900 used by French Bee were claimed by their respective airlines to have greater fuel and energy efficiency compared to other similar or older long-haul widebody aircraft, while flying with a smaller payload to be able to achieve the long distance without stopping for additional fuel.

The great-circle route of the longest domestic flight between Papeete and Paris; the longest domestic commercial passenger flight in history (by great-circle distance). To take advantage of prevailing tailwinds, the actual routes flown tended to be more southerly.
