Flights are avaiable from most airports in the UK and Europe taking you into SOFIA or PLOVDIV.
SOFIA has the most flight options and is open year round whereas Plovdiv is only open during the Ski season. Transfer times are approx 3 hours from Sofia and 1 hour from Plovdiv; the drive from Sofia is very easy.
INDIRECT FLIGHTS: It is advisable to book flights early as they get full at peak season. If no direct flights are available, reasonably priced indirect flights can be booked instead. Flights via Paris (Air France), Munich (Lufthansa). Vienna (Austrian Airlines) are amongst the more popular choices.
