Pulkovo Airport (LED) is Saint Petersburg’s main international gateway and typically serves as the city’s premium hub, handling most long-haul and European flights. Major carriers and several full-service and low-cost airlines operate here, so fares can range from budget-friendly to premium depending on carrier and season. The airport sits about 23 km south of the city centre; ground transport includes regular airport buses and minibus shuttles (roughly 30–60 minutes, low-cost), taxis or ride-hailing (around 30–45 minutes, variable fares), and private transfers. Pros: relatively modern facilities and frequent connections. Cons: can be busy during peak periods and longer road times in heavy traffic. Pulkovo is effectively the primary point of arrival for visitors to Saint Petersburg and usually the most convenient for international itineraries. Domestic carriers and some international low-cost providers also use the airport, so travellers often find a mix of price levels. Public buses and suburban trains link the airport to central Saint Petersburg in roughly 30–60 minutes, while taxis offer faster trips depending on traffic for higher fares. The airport’s services are generally comprehensive, but depending on timing you may experience queues at security or immigration during peak travel windows.

Irkutsk International Airport (IKT) serves as the main air gateway for eastern Siberia and typically functions as a regional international hub rather than a large global transfer point. It usually handles a mix of Russian carriers such as Aeroflot and S7 alongside smaller domestic operators flying to Moscow, Novosibirsk, and nearby Siberian cities; seasonal charters to Baikal-area destinations can be common. The airport sits about 45–50 km north of Irkutsk city center; travel by taxi or private transfer generally takes around 40–60 minutes and can be relatively affordable compared with Western cities, while public bus or shuttle options are slower (roughly 1–1.5 hours) and cheaper. Pros: straightforward layout, basic services and direct access for Baikal-bound travelers. Cons: distance from downtown and limited late-night connections compared with major hubs.
