Looking for cheap flights from Kolkata to Tehran? FlightGPT compares live CCU to IKA fares across every connected source — Indian carriers, Gulf hubs, OTAs and trusted travel agents — and shows the cheapest options side by side. Whether you want a Kolkata to Tehran non-stop tomorrow, a last-minute weekend deal or the lowest price three months out, every active Kolkata-Tehran fare is one search away.
Kolkata (CCU) has direct flights to Dubai (IndiGo, Air Arabia, Air India) and Muscat (Air India, Oman Air). From Dubai, Mahan Air and Iran Air both serve Imam Khomeini International Airport (IKA), Tehran's main gateway. Oman Air operates MCT–THR (Tehran Mehrabad, THR) and IKA services, making Muscat a viable second option. A DXB layover of 2–3 hours is standard. Note: Mahan Air operates under sanctions-related restrictions and may not be bookable through all global distribution systems — Iran Air is a safer bet for ticketing via standard online platforms. Confirm the current operational status of Iran Air's DXB service before booking.
Return economy fares from CCU to IKA (via Dubai) in June 2026 range from approximately ₹32,000 to ₹55,000 for itineraries combining IndiGo with Iran Air, depending on season and advance purchase. Business-class options are limited on Iran Air but where available run ₹90,000–₹1,20,000 return. The cheapest periods are generally October–November and February–March, avoiding Nowruz (Iranian New Year, mid-March) when Iranian diaspora travel peaks. Book the CCU–DXB sector early as IndiGo seats sell out on this trunk route; the DXB–IKA sector can be added later, though prices rise as departure approaches.
Kolkata to Dubai (CCU–DXB) takes approximately 4 hours. Dubai to Imam Khomeini (DXB–IKA) is a further ≈ 3 hours 10 minutes. Iran runs on Iran Standard Time (IRST, UTC+3:30) — exactly 2 hours behind IST and 30 minutes ahead of Gulf Standard Time. This unusual half-hour offset means that on a DXB layover you should re-check your gate time in Tehran local time to avoid confusion. The time difference also means that evening departures from CCU can arrive in Tehran by late afternoon the same day (local), which is convenient for onward hotel check-in.
Indian passport holders can obtain an Iranian tourist visa in one of two ways: an eVisa applied online via the Iranian Foreign Ministry portal (eVisa.mfa.ir), or a Visa on Arrival (VoA) at Imam Khomeini airport for a fee of approximately USD 75 (30-day stay). The eVisa is recommended as it avoids queues at arrival. Processing takes approximately 3–7 business days. Note that holders of Israeli stamps or dual US citizens face complications — this does not typically apply to Indian passport holders, but always double-check entry requirements at /visas before booking, as Iranian visa rules can shift with geopolitical developments. Confirm current rules before travel.
Imam Khomeini International Airport (IKA) is located about 35 km south of central Tehran. It is Iran's principal international gateway with a single main terminal. Currency exchange is available at IKA but Iranian Rials are not freely convertible internationally — bring USD or EUR in cash as cards on international networks largely do not work in Iran due to sanctions. Taxi fares to central Tehran (Valiasr Street area) are approximately 700,000–1,200,000 IRR (about USD 15–25 at current street rates). The airport metro Line 1 extension to IKA offers a cheaper alternative into the city at a fraction of taxi cost.
Tehran is a sprawling metropolis of over 9 million with a surprising cultural depth: the National Museum of Iran, the Grand Bazaar, and the spectacular Golestan Palace (a UNESCO site) are all downtown. Day trips to Kashan (3 hours by road) offer stunning Persian garden architecture, and Isfahan — Iran's jewel city — is 4.5 hours from Tehran by intercity bus or a short domestic flight. The best months to visit are April–May and September–October, when temperatures in Tehran range from 15–25°C. Summer (June–August) can hit 35–40°C on Tehran's plateau. Winters are cold and snowy but the Alborz ski resorts north of the city are active.
Iran's economy operates largely outside international banking due to sanctions. Bring physical USD or EUR cash (in good condition — worn notes may be refused) and exchange at the airport or licensed exchange shops (sarafi). International SIM cards do not roam on Iranian networks; local SIM cards are available at IKA for data. Instagram and many Western apps are officially blocked but VPNs are widely used. Dress code is mandatory for women from the moment of landing at IKA (headscarf required in the terminal). Iran is generally very safe for tourists and Indians are well-received — the country has a long historical connection to India via the Mughal empire and Farsi linguistic links.
No. There are no non-stop CCU–IKA services as of 2026. All routes connect via a Gulf hub — most commonly Dubai (DXB) with a layover of about 2–3 hours, giving a total journey time of around 9–12 hours.
IndiGo operates CCU–DXB; Iran Air and Mahan Air fly DXB–IKA. Oman Air covers MCT–IKA/THR for the Muscat connection. Check availability carefully as Mahan Air has distribution limitations due to international sanctions.
Return economy fares range from approximately ₹32,000 to ₹55,000 when booked 6–8 weeks ahead. Peak Nowruz travel (mid-March) and summer push prices higher. October–November and February–March are cheapest.
Yes. Indian passport holders can obtain an Iranian tourist eVisa online (processing 3–7 days) or a Visa on Arrival at IKA (≈ USD 75, 30 days). The eVisa is recommended to avoid arrival queues. See /visas and confirm current rules before booking.
Tehran is 2 hours behind Kolkata (India Standard Time UTC+5:30; Iran Standard Time UTC+3:30). Iran's unusual 30-minute offset means it is 30 minutes ahead of the UAE/Gulf Standard Time (UTC+4).
International credit and debit cards (Visa, Mastercard) largely do not work in Iran due to sanctions. Bring physical USD or EUR cash in small denominations. Exchange to Iranian Rials at licensed sarafi shops for the best rates — hotel exchange rates are usually less favourable.
