TK1 distance and great-circle path
TK1 covers 8,027 km, or 4,988 miles. That makes it a long-haul flight, a widebody route with a full night's flying time. Of the 439 routes we track, it ranks 136 by distance.
The plane leaves Istanbul 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 IST-JFK route appears on a tracker map.
Why TK1 block time differs from cruise time
The schedule allows 11.3 hours from gate to gate. That works out to about 708 km/h. A Boeing 777-300ER cruises faster than that. The gap is taxi time, climbing, descending and holding.
Flying west, this route pushes against the wind. The trip back east is usually shorter, even though the distance is the same. See how timing changes the trip in our red-eye flight guide.
Can the Boeing 777-300ER comfortably fly TK1?
Not really. It uses about 59% 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 TK1
- Time change: you land 7 hours behind the time you left. That is enough to cause jet lag. Here is how pilots handle it.
