London is served by several airports with distinct roles. Heathrow is the largest international hub, typically hosting full-service carriers and intercontinental flights; it’s usually perceived as pricier but convenient for long-haul travel. It sits about 15–25 km west of central London, reachable by Heathrow Express (15–20 minutes), the Tube (45–60 minutes), and taxis or trains (30–60 minutes) with fares varying widely. Gatwick operates as a major international and leisure gateway with a mix of full-service and low-cost airlines; it’s roughly 40–45 km south, reachable by Gatwick Express (30 minutes) or Southern/Thameslink trains (30–60 minutes). Stansted and Luton are primarily budget-focused hubs used by low-cost carriers for European routes; expect longer transfer times—typically 45–90 minutes by dedicated express or coach services—and generally lower fares. London City Airport targets business travelers with short-haul routes from the east, sitting about 10 km from the financial district and offering quick connections (15–30 minutes) by DLR or taxi, often at a premium. Pros across the network include extensive route choices and frequent services; cons can include variable transfer times, peak congestion, and differing levels of on-site comfort depending on the airport.

Fly direct from London to Irkutsk for the fastest, most convenient way to reach Siberia — fewer hassles, no long layovers, and more time to enjoy your destination. While some connecting options can be cheaper, a nonstop trip saves hours and offers a more comfortable journey for business or adventure travel, so consider booking direct for maximum convenience.

Irkutsk International Airport (IKT) serves as the main air gateway for Irkutsk and eastern Siberia, functioning as a regional international hub rather than a large global transfer point. It typically handles a mix of Russian carriers and some international, charter and low-cost services, so fares can be mid-range to budget depending on season and route. The terminal lies about 45–50 km northwest of the city center; transfer options include express and regional buses (about 50–70 minutes), taxis and shared shuttles (roughly 40–60 minutes), with fares usually modest for public buses and higher for taxis. Pros: relatively compact terminal and direct services to popular regional destinations. Cons: distance to downtown can add time and variability in price for private transfers.

In different months, ticket prices from London to Irkutsk vary: minimum — $391 (January 2026), maximum — $530 (December 2025). Typically, the flight costs $474–$1,031.
