Which airlines fly Delhi to Istanbul non-stop?
Turkish Airlines flies daily from Terminal 3 at Delhi to Istanbul Airport (IST), and IndiGo also operates the route; its aircraft and timings have changed several times since 2025, so check the current schedule. Indian airlines have been routing around Pakistani airspace since 2025, which can make their flights longer than Turkish Airlines' on the same route.
What are the best flight timings?
Turkey is 2 hours 30 minutes behind India. Early-morning departures from Delhi land in Istanbul by late morning, giving you most of the day. Turkish Airlines' schedule is built around connections, so the Delhi flight often lines up well with onward flights to Europe, the US and Cappadocia.
Baggage on full-service and low-cost airlines
Turkish Airlines includes meals and checked baggage, with allowances that depend on the fare brand — its cheapest fares can be stricter, so check before you pay. IndiGo includes a checked bag on most international fares but charges for meals and seats.
Getting from Istanbul Airport to the city
Istanbul Airport is about 40 km from Sultanahmet. A taxi takes 45–75 minutes and costs roughly ₹3,000–4,000 at current lira rates. Havaist buses run to Taksim, Sultanahmet and other hubs for roughly ₹500–700 and take 60–90 minutes. The M11 metro connects to the city network and is cheapest, but involves changes with luggage.
When to book, and connecting options
Book 4–8 weeks ahead for April–June and September–October, the best weather months. January–March (outside holidays) and November are usually cheapest. For Cappadocia, add a domestic flight to Kayseri or Nevşehir, about 1 hour 20 minutes. Turkish Airlines' free Touristanbul tours are available on some long layovers, subject to eligibility.
Tips for families and seniors
- Istanbul Airport is very large, with long walks to gates; request wheelchair assistance at booking.
- Apply for the sticker visa 4–6 weeks ahead; slots get scarce before summer.
- Vegetarian meals on Turkish Airlines must be ordered at least 24 hours ahead.
