Sofia, Bulgaria – In a significant move to enhance public transport connectivity, Sofia now offers direct night bus access to both terminals of the capital’s airport.
The N4 night line, operational as of last night, has been extended to serve both Terminal 1 and Terminal 2 of Vasil Levski Sofia Airport, improving access for late-night arrivals and early-morning departures.
The development was announced by Sofia Mayor Vasil Terziev, who said the move is part of a broader effort to make the city’s public transportation more inclusive and responsive to passenger needs. ‘
“The night bus to the airport is no longer just an idea — it’s a reality,” said Terziev. “We’re ensuring that Sofia’s airport is accessible 24 hours a day.”
The N4 will follow a fixed loop, stopping first at Terminal 2, then Terminal 1, before proceeding in two possible directions: toward the city center and neighborhoods “Gotse Delchev” and “Druzhba 2.” Passengers are advised to confirm the direction before boarding to ensure they reach their intended destination.
The night line will run hourly, connecting to other major night bus services (N1, N2, and N3) at the central transfer hub, Knyaz Alexander I Battenberg Square.
This setup enables late-night connections to key districts including “Lyulin,” “Mladost,” “Obelya,” “Studentski Grad,” “Triaditsa,” and “Poduyane.” Additionally, a stop at the Central Station ensures access to long-distance train and intercity bus routes. Large-capacity buses, each holding up to 100 passengers, will be deployed on the line.
Alongside the night service, daytime operations at the airport have also been improved. From today, bus lines No. 84 and No. 184 have been merged into a single streamlined line — No. 84. This unified service will reach Terminal 2 first, then Terminal 1, enhancing clarity and consistency for passengers.
The new Line 84 will run every 12 minutes on weekdays, effectively doubling the previous frequency of the discontinued Line 184. Weekend frequency is set at 20 minutes. The change is expected to ease scheduling confusion and reduce the impact of ongoing driver shortages.
These transport improvements follow long-standing proposals by the civic group and political movement “Spasi Sofia” (Save Sofia), which has pushed for a night line to the airport and merging of airport bus routes for nearly a decade.
The group notes that more than 22,000 passengers pass through Sofia Airport at night each week, along with thousands of workers who require reliable transportation.
With Terminal 2 now handling triple the traffic of Terminal 1, city planners believe the updated service pattern is not just timely, but essential.
