A new Boeing 777-300 delivered on Saturday morning credited Singapore Airlines (SIA) as airways with the largest fleet of Boeing 777 aircraft in the world, said the company in a statement.

Now owning 58 Boeing 777s including 12 B777-300s, 31 B777-200s and 15 B777-200 Extended Range (ER) aircraft, SIA has ordered another batch of 19 777-300 ERs, which are scheduled to enroll since late 2006 onwards, along with purchase rights on up to 13 more.

The new B777-300, arriving in Singapore eight years right after the delivery of the first of its family to SIA, is installed with 332 seats while the 777-300 ER may accommodate 365 passengers, with both typically configured to three classes. Boasting an average age of 64 months among 90 airliners, the fleet of the country's national airlines is one of the youngest in the world, it said.
