Halfway between Santiago and Tahiti sits a speck of volcanic land that quietly underpins one of aviation's boldest routings. Mataveri International Airport on Easter Island is the only diversion option for aircraft crossing the vast, empty stretch of the South Pacific between South America and Oceania — and without it, routes like Qantas's Sydney–Santiago service simply couldn't fly.

Easter Island is arguably the most isolated inhabited place on Earth. The nearest land, the uninhabited islet of Salas y Gómez, is 258 miles east; the closest other populated island, Pitcairn, lies nearly 1,289 miles away. Mataveri is likewise the world's most remote airport, some 1,617 miles from its nearest counterpart in French Polynesia. Its long runway — 10,800 feet, completed in 1987 and once earmarked as a Space Shuttle abort site — can handle widebodies, which is exactly what makes the trans-Pacific crossing feasible.

Why does one small airport matter so much? Modern twins like the Boeing 787 and Airbus A350-900, with its record 370-minute ETOPS rating, can cross oceans, but rules still require a viable place to land if things go wrong. On this route, that place is Easter Island. Chilean regulators even restrict the airspace to a single aircraft at a time near Mataveri, because a problem at the airport would leave no alternative diversion point between Tahiti and South America.

The fragility of this setup became obvious in late May, when an airstairs truck sheared a passenger door off a LATAM 787 parked on the island. With no hangar big enough for a widebody, engineers had to source a replacement door — likely flown in by cargo aircraft — and carry out precision repairs in the open air, battling wind, dust and sea spray. The jet was targeted for a low-altitude ferry flight back to Santiago without passengers.

For travellers, the practical takeaway is this: LATAM is the only airline serving Easter Island, flying roughly ten and a half weekly rotations from Santiago with 787-8s and 787-9s — nearly 297,000 seats across 2025. Qantas flies Sydney–Santiago about four times a week over the same lonely ocean, revived in October 2022 after a pandemic pause. If the moai statues are on your list, you'll need to book through Santiago, and it's worth knowing your itinerary depends on one runway at the edge of the world.
