How to Find Cheap Flights to Bulgaria (Sofia, Varna & Burgas)
Quick answer
For cheap flights to Bulgaria, compare Sofia (SOF) for city breaks and ski trips with Varna (VAR) and Burgas (BOJ) for the Black Sea coast. Spring and autumn are usually the best-value seasons, while July and August cost the most on beach routes. Low-cost carriers serve many European cities, so compare the all-in price including bags.

Choosing your Bulgarian airport
| Airport | Code | Best for |
|---|---|---|
| Sofia | SOF | Capital, city breaks, Rila and Vitosha, access to Bansko ski resort by road |
| Varna | VAR | Northern Black Sea coast and Golden Sands |
| Burgas | BOJ | Southern coast, Sunny Beach, Sozopol |
| Plovdiv | PDV | Old town and culture, with a smaller route network |
Sofia usually has the broadest choice of routes and the best chance of a one-stop connection from outside Europe. If you are heading to the coast in summer, check both Varna and Burgas, because charter and seasonal flights can make one noticeably cheaper than the other.
Best time to fly
Summer is peak for the Black Sea, with warm weather and the highest fares and hotel prices. May, June and September often offer pleasant weather with lower costs. Winter brings the ski season in resorts such as Bansko, Borovets and Pamporovo, with prices rising around Christmas and school holidays, while the quietest months can be the cheapest for city breaks in Sofia and Plovdiv.
Weather and seasonal schedules change, so check which airlines operate on your dates. Many beach routes run only in the warmer months.
How to keep the total low
- Compare low-cost and full-service airlines, then add bags, seats and airport transfers.
- Fly midweek. Tuesdays to Thursdays are often cheaper than weekend departures.
- Use the cheapest-day view on ScanFlyGo to spot low fares across a month.
- Consider an open-jaw ticket, arriving at Varna and leaving from Burgas, to avoid backtracking.
- Book short-haul flights roughly three to eight weeks ahead and earlier for summer and ski season.
Money and entry basics
Bulgaria is a member of the European Union and the Schengen Area, and it adopted the euro at the start of 2026, though you may still see prices in leva on older materials and some cards or machines. Entry rules depend on your nationality, so confirm your requirements with official sources before you travel. Costs for food, local transport and many attractions are often lower than in Western Europe, which helps your overall budget.
Getting around after you land
Sofia has a metro that connects the airport with the centre, and taxis should be booked through an app or an official desk. For the coast, airport transfers are common, and buses link major resorts. Ski resorts like Bansko are reachable by transfer from Sofia, so allow time in winter for road conditions. If you are meeting someone off a flight, track the arrival on ScanFlyGo for a real-time update.
Plan a sensible itinerary
A week can combine Sofia, the Rila Monastery, Plovdiv and a few days at the coast. Keep connections comfortable and avoid cramming too much. Then browse popular routes to see typical flight options from your region.
Seasonal tips for coast, mountains and city
Beach-focused travellers should look at shoulder weeks at either end of summer, when the sea is still pleasant and fares drop. Skiers can save by travelling in early or late season, or midweek, and by booking their flights and transfers together to avoid awkward arrival times. City-break visitors have the easiest time, since Sofia and Plovdiv are enjoyable year-round and winter weekends are often quiet.
Check the opening dates of seasonal resorts and restaurants before you book, because some coastal towns are very quiet outside summer. A flexible plan lets you pick the cheapest week and then choose what to do around it.
