Tahiti is served by Faa'a International Airport (PPT) in Papeete — the only international airport in French Polynesia. It is a medium-sized hub that handles a surprisingly wide range of long-haul flights given the island's remoteness: Air Tahiti Nui and Air France fly direct from Paris (around 21 hours), Air New Zealand serves Auckland and Los Angeles, Aircalin connects Noumea, and United Airlines runs seasonal service from Los Angeles. Hawaiian Airlines connects Papeete with Honolulu. Most visitors from Europe and North America require at least one connection.
From Los Angeles is the standard North American gateway: Air Tahiti Nui and Air France both serve the route in approximately 8 hours. From Sydney, Air Tahiti Nui flies direct (about 6 hours). From Auckland, the flight takes around 4 hours on Air New Zealand or Air Tahiti Nui.
Faa'a Airport sits on a narrow coastal strip just west of Papeete, making it one of the most spectacular airport approaches in the world — the runway is essentially a causeway over the lagoon between two volcanic peaks. The airport is modern and well-organised; immigration and baggage collection are relatively quick compared to larger hubs.
Inter-island connections: Air Tahiti (a separate domestic carrier from Air Tahiti Nui) operates a dense network of inter-island flights throughout French Polynesia. Bora Bora takes 45 minutes; Moorea just 8 minutes. Ferries also connect Papeete to Moorea (25–30 minutes) and several other nearby islands.
Note that Tahiti is not cheap to reach. Airfares are high, and prices at destination rise further with its remoteness. Budget accordingly.
