Cheap Flights from London to Tehran Starting at $100

London is served by several airports, each with a distinct role. Heathrow is the city’s main international hub, handling long-haul carriers and premium airlines; it’s about 24 km west of central London and reachable by the Heathrow Express (15–20 minutes, typically higher fares), Piccadilly Line tube (50–60 minutes, lower fares) or taxis (30–60 minutes, variable cost). Gatwick, a large secondary international airport to the south, caters to a mix of full-service and low-cost carriers and sits about 45 km from the centre; the Gatwick Express takes around 30 minutes to Victoria, while coaches and trains are cheaper but slower. Stansted and Luton are budget-leaning airports serving many low-cost and charter airlines; Stansted is ~64 km northeast with a 45–55 minute Stansted Express to Liverpool Street or coach options, and Luton is ~55 km northwest with shuttle buses from the station plus longer train/coach combinations. London City Airport, small and close to the financial district (about 11 km), is favored by business travellers for its short transfer time—roughly 20–30 minutes by DLR or taxi—though it has limited long-haul service. Pros across the network include wide choice and competition-driven fares; cons can be longer transfers to central London, variable extra fees with budget carriers, and busy terminals at peak times.

Tehran is served primarily by two airports with distinct roles. Imam Khomeini International Airport (IKA) functions as the main international hub for long-haul and many regional flights, typically handling flag carriers and several full-service foreign airlines; it lies about 45–60 km southwest of the city center, with travel times usually around 45–75 minutes by taxi or shuttle depending on traffic and route, and fares that can range from modest fixed taxi rates to higher private-transfer prices. Mehrabad Airport (THR) is closer—roughly 7–10 km west of central Tehran—and is typically used for domestic and some regional services, often by Iran’s domestic carriers; a taxi ride can take 20–40 minutes and tends to be cheaper. Pros: IKA offers international connections and newer terminal facilities, while THR is more convenient for quick domestic transfers; cons: IKA can be far from the center and affected by heavy traffic, whereas THR may feel more crowded and have fewer international amenities.
