Quick answer: Olbia to Penrhyn distance at a glance
Flight distance from Olbia (OLB) to Penrhyn (MXP) is 10,104 miles (16,261 km, 8,780 nm) great-circle using real OpenFlights coordinates, with an estimated nonstop time of 20h 12m and route type ultra-long-haul international. Coordinates are 40.90°, 9.52° → -9.00°, -158.00°, bearing 337° north-west from haversine formula.

The great-circle distance from Olbia (OLB, Italy) to Penrhyn (MXP, Cook Islands) is 10,104 miles (16,261 kilometers, 8,780 nautical miles). This is the shortest path a plane could fly between the two airports, measured along the surface of the Earth using the haversine formula on the airports' real published coordinates (40.90°, 9.52° for OLB; -9.00°, -158.00° for MXP). A nonstop flight on this route is estimated to take about 20 hours and 12 minutes, assuming a typical cruise ground speed of 500 mph including climb-out and descent. The destination lies roughly north-west of the origin (initial bearing 337°), placing the midpoint of this route near coordinates (15.95°, -74.24°).
By route type, this is a ultra-long-haul international flight. Ultra-long-haul routes need dedicated long-range aircraft such as the Airbus A350-900ULR or Boeing 787-9 Dreamliner, and may include a technical refueling stop on the longest sectors. The destination's solar time zone is 12 hours behind the origin (see our time zone tool for the full breakdown). Estimated carbon footprint per passenger is about 909 kg CO₂ in economy, and the route difficulty score is 9/10.
Great-circle route from Olbia (OLB, 40.90°, 9.52°) to Penrhyn (MXP, -9.00°, -158.00°). The dashed line is the shortest path between the two airports on the Earth's surface — the path a nonstop flight would follow. The midpoint at (15.95°, -74.24°) gives a sense of which region the flight overflies.
How this distance is calculated
TripRoute computes the great-circle distance between two airports using the haversine formula applied to each airport's published latitude and longitude from the public OpenFlights airports.dat dataset (the same data that powers airline route maps worldwide). The haversine formula accounts for the curvature of the Earth, so the result is the true shortest distance along the surface — not a straight line on a flat map. We express it in statute miles (10,104 mi), kilometers (16,261 km, conversion factor 1.60934), and nautical miles (8,780 nm, factor 0.868976). The estimated flight time assumes a ground speed of 500 mph including the climb and descent phases, which is a reasonable average for subsonic commercial jets — actual flight time varies with winds, routing, and the specific aircraft type. The compass direction (north-west, bearing 337°) is the initial great-circle bearing from origin to destination; the path curves slightly because of the Earth's curvature on long sectors.
TRWhen distance matters most for OLB → MXP
At 10,104 miles this is an ultra-long-haul — avoid tight connections; the carbon and jet-lag cost of a second takeoff outweighs a modest fare saving.

Olbia to Penrhyn — quick answers
How far is Olbia from Penrhyn by plane?
The nonstop flight distance from OLB (Olbia) to MXP (Penrhyn) is 10,104 miles (16,261 km, 8,780 nautical miles), measured as a great-circle line across Earth's surface using the airports' published coordinates. This haversine calculation accounts for Earth's curvature and matches airline navigation charts; actual flown distance is slightly longer due to airways and winds.
How long does it take to fly from Olbia to Penrhyn?
Estimated nonstop flight time is 20 hours and 12 minutes, assuming a typical jet cruise speed of about 500 mph including climb and descent. Gate-to-gate time is usually 20–35 minutes longer for taxi and air-traffic routing, and connecting itineraries add 1–4 hours depending on layover length and airport connection efficiency.
Is OLB to MXP a short, medium, or long-haul flight?
This is a ultra-long-haul international flight (10,104 miles). Ultra-long-haul routes need dedicated long-range aircraft and may require a technical stop on the longest sectors. Flight categories follow industry distance bands that predict aircraft type and service level, so you can anticipate cabin options and connection likelihood.
