On 19 December 2000, the supervisory board of newly restructured Airbus voted to launch an € billion ($10.7 billion) project to build the A3XX, re-designated as A380, with 50 firm orders from six launch customers. The A380 designation was a break from previous Airbus families, which had progressed sequentially from A300 to A340. It was chosen because the number 8 resembles the double-deck cross section, and is a lucky number in some Asian countries where the aircraft was being marketed. The aircraft configuration was finalised in early 2001, and manufacturing of the first A380 wing-box component started on 23 January 2002. The development cost of the A380 had grown to €11–14 billion when the first aircraft was completed.
