Seat Map Bulgaria Air Airbus A319

Initially a little concerned having been changed from a PG flight I was encouraged by the punctuality of the aircraft. Layout differed to that expected with ony 2 rows in business class, not 3, which was a pity given that we were in 3a and 3b. Can't give a fair assessment on the inflight attendants, they were PG employees. The seating was very good, faux leather (I can't believe it was real leather!) with ample leg room and the aircraft was very tidy. The pilot, clearly very experienced, landing the aircraft very softly but he was very 'shy' in that he never broadcasted to the passengers throughout the flight. Overall, very happy with Bulgaria

Is it possible to change Seat to 21A?
Kind Regards
