The order valued at more than 790 million dollars at list prices, follows a previous order for 10 777-300ERs in September 2005, for a combined total of 13 777-300ERs.
''It is vital that Jet Airways continues to expand its fleet progressively to ensure its leadership position in India's dynamic aviation market,'' said its chairman Naresh Goyal.
''The 777's operating efficiencies and passenger comfort play a pivotal role in our long-haul growth strategy, and will play a pivotal role as we expand our international operations.'' Jet Airways took delivery of its first 777-300ER in April. In December 2006, the airline also placed an order for 10 787 Dreamliners.
The 777 family of airplanes is popular with passengers and airlines because of its fuel-efficient twin-engine design, high reliability, low operating costs, and comfortable and spacious interior. The 777-300ER typically carries 365 passengers up to 14,685 km.
Jet Airways, with more than 330 daily flights to 49 destinations, operates throughout India and has international routes that include London, Singapore, Kuala Lumpur, Bangkok, Colombo and Kathmandu. The airline's current 777-300ERs operate a Mumbai-London route.
