Business aviation specialist Comlux has ordered another corporate Airbus A320neo, taking its orders for the type to four.

The aircraft, designated the ACJ320neo, will be outfitted by Comlux's completion division in Indianapolis, says Airbus.

Comlux's ACJ320neos are powered by CFM International Leap-1A engines.

The agreement means the company has ordered a total of 20 corporate aircraft from the European airframer.

Private customer orders this year had included a single A319neo, two A320neos and an A350-900 by 31 August. Airbus has not confirmed whether the latest of these agreements, an A320neo ordered on 26 August, is the Comlux aircraft.

Airbus's backlog to 31 August shows firm private and government orders for eight A320neos and four A3219neos. The airframer says the total corporate commitment to the A320neo family amounts to 15 aircraft.
