Flights to New Delhi depart from Imam Khomeini International Airport (IKA), not Mehrabad. Confirm the terminal and arrive around three hours before departure for international check-in, baggage, security and exit formalities.
When a nonstop service operates, the flight is usually about 3 hours 40 minutes to 4 hours. Connecting itineraries can take far longer, so check the number of segments, total elapsed time and transit conditions before booking.
The destination is Indira Gandhi International Airport, code DEL. Check both DEL and the terminal on your ticket, because Delhi's terminals are separated and a domestic connection may require a terminal transfer.
The Airport Express metro links Terminal 3 with New Delhi station in roughly 20 minutes. Prepaid taxis, app-based cars, buses and private transfers are alternatives; allow much more time by road during peak traffic.
Most travellers need the appropriate Indian visa or entry authorization before departure. Eligibility and document rules depend on nationality and purpose, so confirm current official requirements and ensure the passport details exactly match the booking.
New Delhi is two hours ahead of Tehran. Check the local arrival date when reserving your first hotel night, airport pickup, train or domestic connection.
Allow a generous buffer for immigration, baggage collection, customs, terminal transfer and fresh security. If the flights are on separate tickets, consider several hours or an overnight stay because the second airline may not protect you after a delay.
Yes. Dense fog and low visibility can cause delays or schedule changes, especially on winter mornings. Recheck your flight status, keep the first day flexible and avoid a short onward connection during periods of poor visibility.
Confirm your fare's baggage allowance and any rules for medicines, food, samples or batteries. Keep some payment backup, the hotel address offline, and a working connectivity plan; do not assume every foreign card or familiar app will work immediately.
