SOF-Varna return in Business Class (operated by Hamus International Airlines). At SOF airport separate Business Class Security Check. Very nice lounge from where Business Class passengers are picked up and delivered to aircraft. Older AVRO Jet inside completely coloured with white paint. Very wide seats (mechanics a bit worn out) spacious leg room. Drink and Snack offered on 50 minutes flight. Very attentive and friendly staff. Present (bottle of wine and some cosmetics) on departure. A very good experience at € 230 for both ways in Business class!
