Burgas is served by Burgas Airport (BOJ), the primary airport for Bulgaria's southern Black Sea coast and a major seasonal tourist gateway. Flight availability and pricing are highly seasonal, with a vast network of affordable charter and scheduled arrivals operating during the summer peak (May–October) and significantly reduced service in the winter. If you're visiting the Black Sea coast in summer, BOJ can be very cheap; if you're coming in winter, expect few options.
The most frequent and affordable flights into Burgas are seasonal tourist charters and scheduled services from across Europe. Key arrival routes connect to major hubs and cities in the UK (London-STN, LTN, MAN), Germany (Berlin, Frankfurt, Munich), Poland (Warsaw, Katowice), Scandinavia (Oslo, Stockholm, Copenhagen), and the Czech Republic (Prague). Year-round, there are very limited scheduled arrivals — mainly from Sofia (SOF) and a handful of other European cities (often just Istanbul or Vienna with low frequency).
The summer arrival market at BOJ is dominated by European low-cost carriers like Ryanair, Wizz Air, and easyJet, alongside numerous charter airlines (TUI, Jet2, etc.). These airlines create intense competition on popular routes from the UK, Germany, Poland, and Scandinavia, leading to very low fares — sometimes as low as €20–30 one-way. Bulgaria Air typically operates the core domestic route from Sofia (SOF), but this is mostly useful for travelers already within Bulgaria.
To find cheap flights to Burgas for summer European arrivals, book 2–4 months in advance for the best prices on scheduled airlines. However, last‑minute charter deals can also appear if tour operators are trying to fill seats — but this is risky if you have fixed dates. For the limited winter schedule, book as early as possible, as flights are few and fill up. Be extremely flexible with dates and consider flying into Burgas on weekdays (Tuesday–Thursday) for lower fares. For year‑round travel or if your origin city isn't served by BOJ's seasonal network, a common strategy is to take a cheap flight to a major hub like London, Berlin, or Vienna, and then connect from there to Burgas — but note that many of those connecting flights only run in summer. Alternatively, fly into Sofia (SOF) year‑round and then take a bus or train to Burgas (about 5–6 hours), which is reliable and often much cheaper than a winter flight.
