Sofia Airport (SOF) is Bulgaria’s main international gateway and typically serves a mix of legacy carriers, low-cost airlines and regional operators, making it a practical hub for both business and leisure travelers. Located about 10–12 km east of the city center, transfer times are commonly 20–30 minutes by taxi and 30–40 minutes by public transport; Sofia Metro Line M2 and buses provide regular connections with fares generally modest. Passenger facilities can be straightforward rather than luxurious, with useful shops and lounges but occasional crowding during peak hours. Advantages include frequent low-cost routes and quick access to central Sofia, while downsides can be variable wait times and limited premium amenities compared with larger European hubs.

London is served by several airports with distinct roles. Heathrow (LHR) is the primary international hub, typically handling long-haul and full-service carriers and often priced higher than secondary airports; it sits about 25 km west of central London and is reachable by the Heathrow Express (15–20 minutes, premium fares), the Elizabeth Line (30–40 minutes, mid-range fares) and road/taxis (variable time and cost). Gatwick (LGW), roughly 45 km south, commonly serves both leisure and international low-cost carriers with frequent trains to Victoria or London Bridge (30–50 minutes, moderate fares). Stansted (STN) and Luton (LTN) are budget-oriented and usually host low-cost airlines; expect coach or train connections taking 40–80 minutes with lower fares but less comfort. London City (LCY) acts as a business-focused airport close to Docklands (about 10 km from central London), typically favored by short-haul business services and offering quick DLR/taxi links (15–30 minutes). Pros and cons vary: Heathrow and Gatwick offer extensive facilities and connections but can be busier and pricier, while Stansted, Luton and Gatwick can be cheaper but farther out with longer transfer times; London City trades extensive route choice for proximity and speed. Transit fares and durations can vary by operator and time of day, so plan accordingly.

In different months, ticket prices from Sofia to London vary: minimum — $25 (October 2026), maximum — $55 (September 2026). Typically, the flight costs $41–$46.
