Singapore Airlines has re-fitted seven of its Boeing 777-300 aircraft with new first and business class seating.

The new configuration features:

First class: The old 18 seats replaced with eight fully-flat beds in a 1-2-1 configuration (each with a width of 35 inches), the same product currently available on the carrier's B777-300ER aircraft.

Business class: The same seat as recently introduced on SIA's new A330-300 aircraft, a leather lie-flat seat with six-way adjustable headrest and lumbar support.

The economy class cabin features new seat covers designed by Givenchy. In-flight entertainment enhancements include audio visual on demand in all classes, as well as larger screens in business (15.4 inches) and first class (23 inches).

The refurbished aircraft began operating on the Singapore-Sydney service (flights SQ231 and SQ232) from July 22, 2011, with routes to Dubai, Shanghai, Riyadh and Istanbul due to follow.

Note that SIA’s B777-300 aircraft are not be confused with the carrier’s B777-300ER fleet, which operate on routes including London-Singapore. These aircraft feature the airline’s spacious fully-flat business class product which is configured 1-2-1 across.
