Overview
Tehran, Iran's sprawling capital, sits on a high plateau beneath the snow-capped Alborz mountains and rewards visitors with world-class museums, layered Persian history and some of the warmest hospitality anywhere in the region. It is a genuine long-haul trip from the UK with no direct service, so a little planning pays off. Before booking, note that the Foreign, Commonwealth & Development Office (FCDO) currently advises against all travel to Iran; always check the latest guidance and talk to our team about your options.
Best time to fly to Tehran
Spring (April to May) and autumn (late September to October) are the sweet spots, with mild days, clear mountain air and blossom or golden light across the city's parks. Summers are hot and dry, often above 35°C, while winters bring snow to the northern hills and occasional sub-zero nights. Fares tend to ease outside the Nowruz (Persian New Year) holiday around 20 March and the European summer peak — the When to book chart above shows how prices move through the year.
Airlines and routes
There are currently no direct flights from the UK to Tehran, so you will connect through your airline's hub. Common one-stop options include Turkish Airlines via Istanbul, Qatar Airways via Doha, Pegasus Airlines via Istanbul Sabiha Gökçen, and Lufthansa via Frankfurt or Munich. Pure flying time from London is around seven hours; allow roughly 9 to 14 hours in total from London or Manchester once you factor in the connection.
Things to do in Tehran
Give yourself a few days to take in the highlights:
- Golestan Palace: A UNESCO-listed Qajar-era complex of mirrored halls and tiled courtyards.
- Grand Bazaar: A vast covered maze of carpets, spices, gold and tucked-away tea houses.
- National Museum of Iran: The country's leading collection of ancient Persian artefacts.
- Treasury of National Jewels: A dazzling vault of crown jewels held beneath the central bank.
- Tabiat Bridge and Darband: A striking modern footbridge and the trailhead for walks into the Alborz foothills.
At Imam Khomeini International Airport (IKA)
IKA lies about 30km south-west of the city and handles almost all international flights, while domestic services mostly use Mehrabad. A pre-booked airport taxi or an official metered taxi takes 45 minutes to an hour into central Tehran, longer in rush hour. Tehran Metro Line 1 also reaches the airport, but with only a handful of departures a day, so check the timetable before relying on it.
Top tips for finding cheap flights to Tehran
- Book roughly two to four months ahead for the best balance of price and choice; last-minute long-haul fares to Iran are rarely a bargain.
- Fly midweek and avoid Nowruz and school holidays — the price charts on this page highlight the cheaper windows.
- Keep your dates flexible and compare a few connecting hubs, as Istanbul and Doha routings often undercut European ones.
- Compare airlines side by side rather than assuming one carrier is always cheapest, and set up a fare alert.
Travel essentials
UK passport holders need a visa for Iran, and British nationals are normally required to travel on an organised tour or with an approved guide, so arrange this well in advance. Carry a passport with at least six months' validity. The currency is the Iranian rial, though prices are often quoted in toman; because of sanctions, Western bank and credit cards do not work, so bring enough cash (euros or US dollars) to exchange, or use a dedicated tourist card. There are no mandatory vaccinations for most travellers, but check NHS Fit for Travel and current FCDO advice before you commit.
