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 439 routes we track, it ranks 290 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.

What to know about B6703

Time change: none. Both cities keep the same clock, so arrival time reads exactly as you expect.

B6703 against the rest of the JFK-SJU pairing

We track 2 scheduled services between New York and San Juan, split between Delta Air Lines and JetBlue Airways. Among them, it is the only one flown with an Airbus A320.

Measured against B6703, which pushes back at 08:29:

DL806 (Delta Air Lines) runs the same pairing, on an Airbus A321.

Block time is gate to gate, so it counts taxi at both ends. That is why two flights covering identical distance rarely share a scheduled duration.

How much CO2 does B6703 emit?

Worked from the great-circle distance and the fuel burn measured for Airbus A320, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown	2,578 km
Aircraft	Airbus A320
Fuel burn rate	2.91 kg per km
Fuel burned	7,512 kg
CO2, whole flight	23.7 tonnes
Seats, typical layout	150
Passengers carried	124 at an 83% load factor
CO2 per passenger	191 kg

Where that lands by cabin

The aircraft burns the same fuel whoever is aboard, so the cabins divide one total rather than each carrying their own. A seat's share is the floor it takes up, which is why an economy seat comes out below the 191 kg cabin average and a flat bed well above it.

Economy132 seats, 110 flown

155 kg CO2 per seat

3 trees absorbing for a year

Business18 seats, 15 flown

448 kg CO2 per seat

7 trees absorbing for a year

Taken whole, B6703 emits what 396 trees take back out of the air in a year. One economy seat on it accounts for about the same carbon dioxide as driving a petrol car 1,126 km, or 5,470 km of the same journey by train.

How this is worked out. Fuel burn is read from published measurements of this type, taken at a 3,984 km sector, the only published sector for this type, applied to this route's 2,578 km unadjusted. It counts carbon dioxide only, and the cabin split assumes the layout typical of this size of aircraft. Read the full method, sources and caveats, or put B6703 against another flight.
