Airbus adopted a cautious stance on aircraft output on Monday, telling the airline and leasing industry that it would examine supply chain and other conditions before deciding further increases in output of its popular A320 narrow-body series.

The comments by sales chief John Leahy at an industry event came after both Airbus and its rival Boeing said recently that they were studying further increases. Boeing has indicated it might lift production of its 737 series to 52 planes a month in 2018, rising from 42 a month now. Airbus is looking at whether it can manage 50 a month.
