The aircraft fleet is to be renamed after local towns and cities over the next two years. The names will be featured on the aircraft fuselage, with cabin interiors showing the coat of arms of the town or city. The latest fleet addition, an Airbus A330, is the first to follow this scheme, as Berne.
Six Airbus A340 aircraft are to be added to the fleet. The first of which is an ex-Air Canada plane. Three more ex-Air Canada A340s are to be added along with two ex-Austrian Airlines to increase frequencies on existing routes and to launch new routes for summer 2008.
Two Airbus A330 aircraft are also being added to the fleet. The first one will replace an Airbus A300-600 in November 2006 which was leased from Hapag-Lloyd, and the second in mid-December 2006, both to increase route frequencies.
The short haul fleet is also expected to expand with plans confirmed in September 2006 to add two Airbus A321 and one Airbus A320 aircraft. To avail the market chances, Swiss added 2 additional Airbus A320 aircraft to their fleet earlier than planned. The aircraft were added in autumn 2007 and were not new-build aircraft, but rather former Swissair aircraft that were leased out for six years.
On 20 September2007, Lufthansa confirmed an order for 41 aircraft. Two of the ordered A320 and the 9 orders for A330 aircraft are intended for Swiss.
One MD-11 aircraft formerly used by Swiss had the Chinese character Ruì (瑞), from the Chinese translation of Switzerland, Ruìshì (瑞士), on the tail fin instead of the cross. It came from the former Swissair subsidiary Swissair Asia, which was formed to allow for Swissair to serve the Republic of China and the People's Republic of China .
