Bulgaria has good air links with numerous European cities, as well as some cities in the Middle East. There are currently no direct flights to Bulgaria from further afield, so visitors from, for example, North America or Australia will need to pick up a connecting flight elsewhere in Europe.
Sofia Airport (www.sofia-airport.bg) is the main point of entry to the country. Varna Airport (www.varna-airport.bg) and Burgas Airport (www.bourgas-airport.com) serve the coast, and are particularly busy during the summer when they are used by charter flights. For central Bulgaria, direct flights from a couple of European cities, including London, reach Plovdiv Airport (www.plovdivairport.com).
The national carrier is Bulgaria Air (www.air.bg). It has an unblemished safety record, and operates flights to destinations across Europe (including London, Paris, Frankfurt and Madrid) and the Middle East, as well as domestic routes to the Black Sea coast.
