Airbus has revealed a new memorandum of understanding for 100 A320neo-family jets, without identifying the customer.
However, the airframer does indicate that the deal would add to the customer's "existing orders for the type".
The 100 aircraft comprise 75 A320neos and 25 A321neos.
Engine selection will be made at a later date, says Airbus.
