Airbus has delayed the delivery of its first A320neo aircraft by "a few days", a spokesman said on Wednesday, missing the goal to hand over the jet to its initial customer by the end of 2015.
"Discussions are continuing such that when we deliver the plane, it is truly operational in the Lufthansa fleet," the Airbus spokesman said. "It will take a few days."
Lufthansa is to become the first airline due to take delivery of the A320neo passenger jet earlier this month after Qatar Airways questioned technical performance of the engines.
Lufthansa said it had agreed with Airbus to delay the delivery to the start of 2016 due to "technical complexities".
Airbus said this related to delays in providing documentation.
