CX520 route overview: HKG to NRT

CX520 distance and great-circle path

CX520 covers 2,963 km, or 1,841 miles. That makes it a medium-haul flight, long enough for a full meal service, short enough for narrowbodies. Of the 255 routes we track, it ranks 186 by distance.

The plane leaves Hong Kong heading north-east. On the map above, the line looks curved. That is normal. The shortest path over a round planet never looks straight on a flat screen. Our guide explains how the HKG–NRT route appears on a tracker map.

Why CX520 block time differs from cruise time

The schedule allows 3.9 hours from gate to gate. That works out to about 756 km/h. An Airbus A330-300 cruises faster than that. The gap is taxi time, climbing, descending and holding.

Flying east, this route usually picks up tailwinds high up. The flight back west normally takes longer, even though the distance is identical. See what really moves flight times.

Can the Airbus A330-300 comfortably fly CX520?

Not at all. At roughly 25% of its range, this is an easy trip for an Airbus A330-300. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Airbus A330-300.
