Air One, which ceased operations effective Oct. 30, 2014, did not operate any Airbus A330 aircraft. Its fleet and outstanding aircraft orders were transferred to its parent company Alitalia, which has seat maps of its aircraft available for download from its website.
As of October 2015, Alitalia's website provides seat maps for aircraft including the Airbus A330-200 and the Airbus A320 Air One. The seat map for the Airbus A330-200 shows two configurations: one for a two-class, 283-passenger cabin and one for a three-class, 256-passenger cabin. The seat map for the Airbus A320 Air One shows a single-class, 180-passenger cabin.
Founded in 1983 as Aliadriatica, Air One officially merged with Alitalia in 2009. Alitalia operated Air One Smart Carrier as a subsidiary brand from 2010 to 2014. When its operations ceased, Air One had a fleet of 10 Airbus A320s with another 24 aircraft, including 12 A330s, on order from Airbus.
