Mahan Air is the principal non-stop operator on Delhi–Tehran, flying a few times a week (commonly midweek and weekend departures) into Imam Khomeini International — frequencies are limited, so book early and confirm the day pattern. Iran Air has historically also served the India–Iran market. When the non-stop is full or badly timed, the Gulf hubs fill in: Qatar Airways via Doha, Emirates via Dubai, Oman Air via Muscat and Gulf Air via Bahrain all connect Delhi to Tehran with a single stop. These add several hours but run far more frequently than the limited direct service.
The non-stop Delhi–Tehran flight covers about 2,470 km in roughly 4 hours. Tehran is 1 hour 30 minutes behind India, so a late-night Delhi departure lands in Tehran in the early hours local time. One-stop Gulf routings via Doha, Dubai, Muscat or Bahrain push the total to roughly 8–12 hours depending on the layover, so the Mahan Air non-stop is much quicker when its schedule lines up with your plans.
Iran's best travel weather is spring (March–May) — including the Nowruz new-year period in late March, a major peak — and autumn (September–November). Summers are hot inland and winters cold in the mountains. Pilgrimage and religious-calendar travel also lifts demand at times. Because the non-stop runs only a few days a week, its fares can rise quickly when seats are scarce, so booking early is the surest way to secure both a good price and a convenient date. Verify pricing live, as currency and sanctions factors make Iran fares volatile.
Lock in the Mahan Air non-stop early for Nowruz and autumn travel, when limited seats sell out. If your dates are flexible, compare the direct flight against a Gulf one-stop — occasionally Qatar or Oman Air pricing is competitive, and you gain frequency at the cost of time. Travelling light helps where fares bundle less baggage. Note that paying for travel inside Iran can be tricky for foreigners, so budget for cash. Open the FlightGPT search to compare live options on your exact dates — we never quote a fixed fare because prices on this route move sharply.
Delhi flights depart from Indira Gandhi International Terminal 3 (T3); arrive about 3 hours ahead. Tehran's main international gateway is Imam Khomeini International Airport (IKA), about 30 km southwest of the city — not to be confused with the older domestic Mehrabad airport (THR) closer to the centre. From IKA, official airport taxis and the metro extension link you to central Tehran; agree the taxi fare in advance, and carry the address of your hotel written in Farsi to help drivers.
Allowances depend on the carrier and fare. Mahan Air economy on this route typically allows a checked allowance in the region of 30 kg + cabin, though this varies — confirm with the airline. Gulf carriers on one-stop routings generally offer 2 x 23 kg + 7 kg cabin in economy (Qatar, Emirates, Oman Air). Always verify the exact allowance for your specific ticket, and weigh bags carefully, as excess charges on these sectors can be steep.
This is the key planning point: Iran suspended its visa-free entry for Indian passport holders from 22 November 2025, so you now need a visa to enter. The two main routes are an e-visa obtained in advance through Iran's official e-visa portal (evisa.mfa.ir), or a visa on arrival — but the visa on arrival now requires a pre-approved Visa Grant Notice (authorisation code) arranged beforehand via the e-visa portal or a travel agency; you cannot simply turn up without it. A standard tourist visa typically allows a 30-day stay, with a visa-on-arrival fee around €90 paid at the airport. Always reconfirm the current process on the official portal before you travel.
Because the Mahan Air non-stop runs only a few days a week, the Gulf hubs are the practical fallback. Qatar Airways via Doha and Oman Air via Muscat offer convenient connections and good service; Emirates via Dubai and Gulf Air via Bahrain add further frequency. Keep at least 90 minutes for the transfer, and on a through-ticket your bags are checked to Tehran. These routings also suit travellers combining Iran with a Gulf stopover.
Iran is warm and welcoming to Indian visitors, but plan around its practicalities. International bank cards do not work in Iran, so carry enough cash (euros or US dollars to exchange) for your whole trip. Women must observe the hijab/headscarf rule in public. Tehran is the springboard for Iran's classic circuit — Isfahan, Shiraz, Persepolis and Yazd — reachable by cheap domestic flights, trains and buses. Download an offline map and a translation app, as English is limited, and respect local customs and dress codes throughout.
Iran offers one of Asia's richest cultural journeys — the turquoise domes of Isfahan, the ruins of Persepolis near Shiraz, the desert architecture of Yazd, lavish Persian gardens and legendary hospitality. For Indian travellers there are deep historical and religious ties, including pilgrimage to Shia holy sites. With direct Mahan Air flights and easy Gulf connections, Tehran is the gateway to a country that consistently surprises first-time visitors with its beauty and warmth.
