Hi, I do not expect this feature to be in the NGX, but I would like to find out more about the details, equipment of such a package. If there be anyone who knows, please kindly share your knowledge. Many thanks,Raymond

Isn't that the same as the high altitude package?

Quoted fromhttp://flighttraining.aopa.org/careerpilot/industry_news.html

Boeing has delivered a Next-Generation 737-700 to Xiamen Airlines that incorporates both the high-altitude/high-temperature airport operations feature package and the new Boeing Sky interior. It marks the 50th Boeing airplane directly ordered by and delivered to Xiamen Airlines. China is one of the few regions that operates high-altitude airports. The high-altitude/high-temperature package includes a new engine thrust rating, which provides additional payload capability at high-altitude airports and in hot conditions, like those found in the Tibetan plateau. The package also includes an extended-duration oxygen system. The Sky interior features LED lighting and expanded pivot bins, which enable passengers to load more baggage. Xiamen Airlines currently operates an all-Boeing fleet with Next-Generation 737-700s, -800s and 757-200s on more than 100 domestic and international routes; to date, it has ordered 83 airplanes from Boeing.
