Airbus's slow order activity failed to pick up in May, during which the airframer gained business for just a single A320neo.
The agreement is for the corporate ACJ320neo version of the single-aisle twinjet.
It barely made any difference to the negative net order figure of 57 aircraft recorded by the company over the first five months of the year.
The airframer has taken orders for 43 long-haul and 25 single-aisle aircraft since the beginning of this year, but suffered heavy cancellations including more than 70 A350s and A380s.
But the imbalance could be rectified, to an extent, during the upcoming Paris air show, an event at which Airbus has typically used to unveil significant order agreements.
The airframer will be keen to generate publicity at the show, on its home turf, particularly given that it is marking its 50th anniversary and the Paris event will be the first since Airbus appointed new individuals to several senior management roles.
Airbus has delivered 313 aircraft so far this year, 90 more than it had at the same point in 2018.
These included 255 single-aisle jets – of which 15 were A220s – plus 12 A330s, 43 A350s and three A380s.
