St. Petersburg to Istanbul
2h 59mgate to gate
The flight from Pulkovo Airport (LED) to İstanbul Airport (IST) covers 2,063 km (1,282 miles) and takes approximately 2h 59m gate to gate for a typical jet.
The route heads south on an initial great-circle bearing of 184°, passing near 50.5° N, 29.3° E at its midpoint.

How this is worked out
- Take both airports' published coordinates from OurAirports — nothing here is scraped from another flight site.
- Great-circle distance by haversine on a mean earth radius of 6,371.0088 km: 2,063 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 2h 34m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 2h 59m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
2,063 km / 805 km/h = 2h 34m airborne
+ 25 min ground = 2h 59m gate to gate

The same route, plotted on a world grid
The strip above gives the route its length and its shape. This gives it a position: latitude and longitude only, no coastlines, because a hand-drawn coastline would be decoration pretending to be data. On a flat grid the shortest path looks bent; on a globe it is straight.
Flight time at different cruise speeds
Aircraft type, winds and routing all move the real number. This is the same distance flown at different speeds, plus the 25-minute ground and climb allowance.
| Typical of | Cruise speed | Airborne | Gate to gate |
|---|---|---|---|
| Turboprop / regional | 550 km/h | 3h 45m | 4h 10m |
| Narrowbody jet (A320, 737) | 780 km/h | 2h 39m | 3h 04m |
| Widebody jet (777, 787, A350) | 900 km/h | 2h 18m | 2h 43m |
| Private jet (Gulfstream) | 850 km/h | 2h 26m | 2h 51m |
Headwinds on an eastbound long-haul routinely add 30–60 minutes; the same route westbound can be quicker. Airlines publish schedules with padding built in.

Questions this plate answers
How long is the flight from St. Petersburg to Istanbul?
A non-stop flight from St. Petersburg (LED) to Istanbul (IST) takes about 2h 59m. The great-circle distance is 2,063 km (1,282 miles, 1,114 nautical miles), flying south on an initial bearing of 184°.
How far is St. Petersburg from Istanbul?
2,063 kilometres in a straight line over the earth's surface — 1,282 miles or 1,114 nautical miles. Actual flown distance is usually 2–5% longer because aircraft follow airways, avoid weather and route around restricted airspace.
Is there a non-stop flight between LED and IST?
This page calculates the direct-line time and distance; it does not track airline schedules. At 2,063 km the route is comfortably within range of a non-stop service if an airline chooses to fly it. Check an airline or booking site for what is actually scheduled.
Airport coordinates from OurAirports (public domain). Distance is a great-circle calculation; flight time uses the model described on the method page. Flight times are great-circle estimates for planning only — always check the airline's published schedule.
