Delhi to Istanbul Flights

What's new in Delhi

• October 2025: The rebuilt Terminal 2 at Indira Gandhi International Airport reopened on 26 October 2025 after a closure that began in April 2025, and a share of IndiGo and Air India domestic flights moved into it. Check the terminal printed on the boarding pass before leaving for the airport.
• February 2026: The full 82 km Namo Bharat regional rail corridor from Sarai Kale Khan to Modipuram in Meerut was inaugurated on 22 February 2026, giving south-east Delhi a fast rail link to Ghaziabad and Meerut.
• June 2026: Noida International Airport at Jewar (DXN) began scheduled flights on 15 June 2026, with IndiGo operating the first service. For some domestic routes it is a practical alternative for travellers based in Noida and Greater Noida.

Tips for travellers

For a two or three day stay, Connaught Place, Paharganj and Karol Bagh sit on the Blue and Yellow metro lines, while Aerocity suits early departures because it is next to the airport. The Delhi Metro is the quickest way across the city, and a smart card or a QR ticket bought on a phone saves time at the counters. October to March is the main sightseeing season, though smog can be heavy in November, and Diwali week fills hotels and trains. May and June are extremely hot.

The Red Fort is closed on Mondays. At Jama Masjid and Gurudwara Bangla Sahib, remove your shoes and cover your shoulders and legs; the gurudwara also asks everyone to cover their head and lends scarves at the entrance. Swaminarayan Akshardham does not allow phones or cameras inside, so leave them in the cloakroom or at the hotel.

Tips for travellers from India

Sultanahmet is the most direct base for Hagia Sophia, the Blue Mosque and nearby historic streets. A stay near Taksim instead favours the northern side of the central European districts, while Kadıköy provides an Asian-shore base reached by ferry or rail. Istanbul Airport is northwest of these areas; Sabiha Gökçen is a separate airport on the Asian side. A connection involving both needs a cross-city transfer.

The airport metro connects through Gayrettepe, where onward city rail serves other districts. In June 2026, the final Halkalı–Arnavutköy section opened, extending the airport railway towards Halkalı and giving passengers another western connection. Choose the interchange for the final hotel rather than assuming the airport train runs directly to Sultanahmet. The Grand Bazaar fits into a historic-peninsula day, while a Bosphorus ferry ride can be planned around an actual destination on the opposite shore. A scheduled public ferry and a sightseeing cruise offer different routes and ticket arrangements. The Blue Mosque is an active place of worship, so visitor access is organised around prayers; Hagia Sophia has separate visitor arrangements. Grouping these sites geographically still requires treating each entrance as a distinct visit. For an early flight, compare the first airport transport departure with the check-in time.
