Airbus Group (AIR.PA) defied warnings of a slowdown in the jetliner market with a steep production boost for its top-selling A320 and announced its biggest ever dividend. The world’s second-largest aerospace group after Boeing (BA.N) said it would increase production of the A320 jet family to a record 50 a month in early 2017. “Airbus has bitten the bullet on the A330,” said Edison Investment Research analyst Sash Tusa, adding that the move was widely expected. Airbus Group Chief Executive Tom Enders dismissed recent market concerns that the commercial aerospace cycle has peaked.
