Airbus Group is continuing to study higher rates of A320 production beyond the output of 46 aircraft per month to which it has already committed.
Speaking during the company's annual general meeting, chief executive Tom Enders said the airframer was "studying higher production rates" which could be introduced after the transition to the re-engined A320neo.
Airbus is already intending to shift from a rate of 42 per month to 44 in early 2016, before raising it to 46 shortly afterwards.
Enders says the production rate could be increased further once the critical A320neo transition period, from 2016-18, has passed.
Airbus had a backlog of 4,240 single-aisle aircraft at the end of April.
