Sofia Airport (SOF) is Bulgaria’s main international gateway and typically serves a mix of full-service carriers, low-cost airlines and regional operators, making it a practical choice for both business and leisure travelers. Located about 10–15 km east of the city center, transfer options include metro (around 20–30 minutes, modest fares), buses or private taxis (20–40 minutes depending on traffic, taxi fares vary), and airport shuttles to major hotels. The airport usually offers a compact terminal with standard amenities and a range of dining and shopping options; pros are quick immigration and good low-cost connections, while cons can include peak-time queues and occasional crowding during holiday periods.
Istanbul is served by two main airports with distinct roles. Istanbul Airport (IST) is the large international hub on the European side, typically handling long-haul and full-service carriers and serving as a transit focal point; it sits roughly 35–50 km from the historic city center, with airport bus lines and taxis taking about 40–60 minutes depending on traffic and costing roughly moderate fares relative to local standards. Sabiha Gökçen (SAW) is a budget- and low-cost-oriented airport on the Asian side, usually favored for cheaper carriers and regional flights; it lies about 40–55 km from central Istanbul, reachable by shuttle services, buses, and taxis in around 50–90 minutes and often at lower out-of-pocket transfer costs. Pros: IST offers extensive facilities and connections, while SAW can be easier for budget fares; cons: both can involve long commutes and variable traffic-related transfer times.
