Cheap flights from London to Tehran

November is the cheapest month on this route, and the price calendar runs from September through April, with June on it as well. Late autumn and winter sit outside the summer rush, so connecting seats are easier to find and fares settle. Flying midweek rather than at the weekend usually costs less, and the weeks around school breaks fill up first. If you can be flexible, watch the calendar for a while before you commit — on a route like this the difference between a good fare and a poor one is often just the day you pick.

Nothing flies non-stop, so the airline you choose decides where you change. Low-cost names such as Pegasus, Ajet and Air Arabia sell the seat on its own, so read what your fare includes before you compare it with a full-service ticket. Lufthansa, Austrian, Emirates and Qatar Airways bundle more into the fare and often route you through a bigger hub, which can mean a longer but smoother connection. Azerbaijan Airlines, Aer Lingus and Iberia sit between the two. On a journey this long, the gap between a cheap-looking fare and a good one is usually the bag and the length of the stop.

You land at Imam Khomeini International, the airport that handles Tehran's international traffic, and it sits outside the city, so the transfer into town is part of the trip rather than an afterthought. Licensed taxis and pre-booked cars meet arrivals; agree the fare or arrange the ride before you fly rather than sorting it out at the kerb. Traffic into Tehran can be heavy at any hour, so build in a buffer before an onward appointment or a hotel check-in. Keep the address of where you are staying written down, in case you need to show the driver.

• Check which London airport you leave from — Heathrow, Gatwick, Luton, Stansted and London City are far apart.
• Read the baggage rules on low-cost tickets from Pegasus, Ajet and Air Arabia before comparing fares.
• Find out whether your connection is on one ticket or two, since a self-transfer means checking your bag in again.
• Sort your passport and visa requirements for Iran before you book.
• Compare total journey time, not just the fare — every option on this route stops somewhere.
• Book early for winter, as November is the cheapest month and the good seats go first.
