There are few Airbus A340s left in the world. Despite only operating four of the exciting and characterful A340-300s, SWISS has the world’s fourth-highest number of flights by them. Only Lufthansa, Iran’s Mahan Air, and Edelweiss have more. Like any older equipment, the A340 has considerably higher fuel burn than the newer twin types. However, it is somewhat offset by much lower lease rates.
