B6703 route overview: JFK to SJU

B6703 distance and great-circle path

B6703 covers 2,578 km, or 1,602 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 191 by distance.

The plane leaves New York heading south. 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 JFK–SJU route appears on a tracker map.

Why B6703 block time differs from cruise time

The schedule allows 3.8 hours from gate to gate. That works out to about 684 km/h. An Airbus A320 cruises faster than that. The gap is taxi time, climbing, descending and holding.

Winds aloft shift the real flight time by up to an hour in either direction. See what really moves flight times.

Can the Airbus A320 comfortably fly B6703?

Not at all. At roughly 42% of its range, this is an easy trip for an Airbus A320. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Airbus A320.
