China’s Hainan Airlines has reported a net income of CNY2.1 billion ($337 million) for 2013, up 9.2% over the net profit of CNY1.9 billion in 2012.
According to the Haikou-based carrier’s filing released by the Shanghai Stock Exchange, operating revenue rose 4.71% to CNY30.23 billion on operating costs that rose 9% to CNY23.5 billion. Industry analysts credited “exchange gains resulting from the yuan appreciation” as the main contributor to the improved performance.
Hainan noted it experienced “a rapid growth of air traffic volume” last year, but said “the worsening external operating environment” and “slowdown of China’s economic growth” hampered revenues. The carrier’s mainline revenue from air transport operation grew only 2.37% to CNY27.51 billion.
Passenger boardings increased 16.4% to 26.2 million with an average load factor of 86.4%, improving two percentage points over the prior year.
Cargo traffic volume increased by 7% to 313,300 tonnes.
Last year, Hainan introduced 27 aircraft and phased out 13 aircraft, leaving a fleet of 131 aircraft comprising of six Airbus A330-200s, seven A330-300s, three Airbus A340-600s and one A330-VIP; plus one Boeing 737-400, five 737-500s, 99 737-800s, three Boeing 767-300s, six Boeing 787-800s.

Rough Numbers Below:
How much Boeing equipment influences the 9% net profit is considerable in that operational efficiency sets the profit pace using efficient aircraft in a highly volatile fuel price world. The aircraft performance must offset that volatility and contribute to the profit line.

Fleet percentage by manufacturer raw units:
87% Boeing
13% Airbus
Contributions to net profit has a perponderance of Boeing Aircraft types for Revenue and Cost sources. During a slower economy, it is remarkable that Hainan has achieved this net profit number. What is import to know is what write-off's are taken and how each cost center contributes to that bottom net profit number. However, it can be said, "That it is positioned well to expand its WWW throughout the Asia region. Expect more 787-# and 737-MAX to be ordered by Hainan retiring the A340's and its remaining A330's and replaced by 787-8,-9 or -10

Looking ahead, the company expects the air transport market to continue to grow, especially in China’s less-developed cities and it believes domestic airports expansion projects will “bring new opportunities”. But domestic low cost carriers will “exert some impact” on traditional legacy carriers although they have become “new growth points” for China’s airline industry.
