SV21 distance and great-circle path
SV21 covers 10,225 km, or 6,354 miles. That makes it an ultra-long-haul flight, near the limit of what most twinjets can fly non-stop. Of the 255 routes we track, it ranks 59 by distance.
The plane leaves Jeddah heading north-west. 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 JED–JFK route appears on a tracker map.
Why SV21 block time differs from cruise time
The schedule allows 12.9 hours from gate to gate. That works out to about 792 km/h. A Boeing 777-300ER 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 how high-altitude winds behave in our guide to turbulence and jet streams.
Can the Boeing 777-300ER comfortably fly SV21?
Not really. It uses about 75% of the Boeing 777-300ER's range. That leaves room for a full load of passengers and bags. The full numbers are on our aircraft page for the Boeing 777-300ER.
What to know about SV21
- Time change: you land 7 hours behind the time you left. That is enough to cause jet lag. Here is how pilots handle it.
