Sun Air Bulgaria

Public sources found in search do not verify “Sun Air Bulgaria” as the operator of IATA AB / ICAO BER; those codes are listed for the defunct German airline Air Berlin. Air Berlin was headquartered in Berlin, used Berlin-Tegel and Düsseldorf as key hubs, belonged to oneworld during its later years, and ran the topbonus frequent-flyer program. For travelers, treat AB/BER as a historical or data-cleanup record rather than a bookable airline: Air Berlin ceased operations in 2017, and any current itinerary, crediting choice, or baggage/service rule should be checked against the actual operating carrier shown on the ticket.
