Airbus knew of the cancellation of a 70 aircraft order from Emirates well in advance of their disclosure during Innovation Days. This is the suggestion of an article published in Challenges (here) by Vincent Lamigeon -that AirInsight translates into English.-
On 8/May, Emirates’ annual report included the A380 and 777X orders but did not include the A350 order.
