Emirates Airline would buy 100 Airbus A380neos if Airbus decided to launch the aircraft, according to airline President Tim Clark.

In a Bloomberg TV interview at the World Economic Forum in Davos, Switzerland, Clark said that he visited Airbus in Toulouse late last week to discuss the A380, among other subjects.

“What we have said as Emirates is if you are going to do the neo, we are in for 100,” he said. “Put it on the table—we will start off for you.”

Clark has been pushing Airbus to commit to the A380neo re-engining project, but Airbus has been slow to respond and Rolls-Royce is likely the only engine manufacturer that would  provide a powerplant for it.

Airbus President and CEO Fabrice Bregier said last week that Airbus would look at putting a new engine on the aircraft as one option to increase its efficiency. But one obvious cost gain—more fuel efficiency and lower fuel costs—would be more negligible if oil prices, which are down nearly 50% from a year ago, remain low.

Separately, Emirates has agreed to pick up four 2016 delivery slots for the A380. They are coming from the aircraft’s only customer in the leasing community, Amedeo. 

The lessor’s CEO Mark Lapidus told Aviation Week that Amedeo has moved the four deliveries originally scheduled for 2016 into 2017 and 2018. Amedeo has also agreed a sale-and-leaseback deal for two of the four additional aircraft that Emirates is now taking next year. The increases the lessor’s A380 commitment to 22 aircraft.

Emirates, far and away the largest A380 customer, has committed to 140 of the 317 A380s sold to date, and had taken delivery of 57 by the end of December. Of the latest tranche of 50 ordered at the 2013 Dubai Air Show, 25 were going to come after 2020, which is seen as a feasible entry-into-service date for an A380neo. 

That timing raises the prospect of Emirates converting some orders for the existing version to the neo if Airbus moves quickly in launching the upgraded version.
