In , the Boeing 737 was supplemented with an Airbus A310. However, a dispute with Bulgarian Jes Air over who should pay for the repairs after the aircraft sustained an engine failure led to its replacement with another A310 from GATX, also operated by Jes Air. A similar dispute with United Technologies encouraged the airline to switch from Airbus to Boeing. Hence, a Boeing 767-200ER, leased from Ansett Worldwide Aviation Services (AWAS), arrived in January 1993, and a Royal Brunei Airlines Boeing 767-300ER, arrived the following year. In October 1993, the first Airbus A320-200 was incorporated over a two-year wet-lease contract with Air France. Vietnam Airlines by now had started discussions with Air France about a partnership, and the French carrier agreed to lease its Airbuses to Vietnam Airlines, and also to provide customer support and pilot/crew training. By that time the route network had further expanded internationally, seeing the incorporation of destinations such as Paris, Tokyo, Seoul, Taipei, Sydney, and Melbourne. In 1993, the airline carried 1.06 million passengers, 418,000 of whom were on international flights.
