Qatar Airways has removed its last Airbus A330 from its passenger fleet. The airline is also offering a voluntary temporary detachment to more than a dozen qualified pilots on this type of aircraft with RwandAir. These decisions come amid disruptions in air traffic in the Gulf and rising fuel costs linked to the war in Iran. According to Reuters, Qatar Airways had leased four A330s from Oman Air in 2025 and planned to operate them until 2026. These four aircraft were ultimately never put into commercial service under Qatar Airways' livery. At least one of these long-haul aircraft was acquired by RwandAir. The German website aeroTELEGRAPH identifies it as an A330-200 now registered as 9XR-WS, after previously being registered as A4O-DC with Oman Air. RwandAir announced in August that it had received the first of five A330s it plans to add to its fleet. A spokesperson for Qatar Airways confirmed to Reuters that a group of A330 pilots is being offered a voluntary short-term detachment with RwandAir. The arrangement is intended to allow pilots to continue flying while meeting the operational needs of both carriers. The company did not specify the duration of the detachments. The two airlines already have commercial ties. Their code-sharing agreement connects their networks via Doha and Kigali. The announced detachment, however, concerns only pilots and not the resumption of A330 flights by Qatar Airways. The removal of the A330s occurs amid rising jet fuel costs since the beginning of the war in Iran. Operating the older A330-200 and A330-300 models has become less attractive. The aircraft still leased to Oman Air are stationed in Doha or Teruel, Spain. The disruptions also affect Qatar Airways' operations. At the beginning of September, its average capacity over seven days, measured in available seat kilometers, was 10% lower than the previous year, and its schedule showed 12% fewer flights, according to Cirium Ascend data. Qatar Airways continues with its fleet renewal. It plans for six aircraft retirements and expects 19 deliveries between September 2026 and the end of 2027, according to its spokesperson. This schedule is separate from the previously announced A330 retirements.
