Korean Air's eco-friendly A330-300 planes

Korean Air, the flagship carrier of South Korea, has introduced its brandnew, fuel-efficient A330- 300 aircraft on its Southeast Asia routes.

It is also planning to introduce three more aircraft by the end of the year.

These three A330-300s will have a revamped prestige class, called Prestige Suites, which will be equipped with privacy panels installed between seats, and features like ottomans for passengers to rest their feet - usually found only in the first-class cabins of other airlines.

In addition, other features like an enhanced inflight entertainment system, mood lights and LED personal reading lamps will enhance the onboard experience of passengers in all classes.
