In Sofia’s public transport system, passengers can pay directly with a contactless debit or credit card (or mobile wallet) by tapping on the validator in buses, trams, trolleybuses, or at metro gates.

Each journey is automatically charged at €0.80 per trip. A daily fare cap of €2.00 applies: once this amount is reached, all additional rides on the same day are free of charge.  The only condition is that you use the same bank card throughout the day.

No ticket or prior registration is required — just tap in and travel.

Sofia Airport is directly connected to the city centre by Metro Line M4. The metro station is located at Terminal 2. Trains run frequently throughout the day, and the journey to the city centre (e.g. Serdika Station) takes approximately 20–25 minutes.

If you arrive at Terminal 1, a free shuttle bus operates between Terminal 1 and Terminal 2 every few minutes.

Public bus services are also available from the airport. Bus line 84 connect Sofia Airport with the city centre and key transport hubs.

Taking a taxi from Sofia Airport to the city center takes about 15–25 minutes, costing roughly €8–€15.
For your comfort and safety, we recommend the services of the taxi operator Yellow! as the contractual partner of SOF Connect, the concessioner of Sofia Airport.

Look for the Yellow! cars at the main taxi ranks or request the service at the offices of Yellow! in the Arrivals of Terminal 1 and Terminal 2.

IMPORTANT! We recommend that you do not use taxi services offered outside the office of the taxi operator or in front of the terminal to avoid the risk of abuse.
