Taiwan's EVA Air is considering expanding its aircraft fleet to cater to growing demand from China.
The company says that it is evaluating the aircraft that are suitable for its needs.
"We will make our final decisions based on how well various aircraft meet our passengers' needs, our quality service and safety requirements," said a company spokeswoman.
The company could purchase 20 new aircraft, its president Chang Kuo-wei told local media.
EVA Air is considering purchasing more narrowbody passenger planes, like the Airbus A321, to replace its older aircraft, he said, without giving a timeframe.
EVA Air started a Taipei-Zhengzhou service on 10 December 2010, utilising the Airbus A330-200 aircraft.
Eva Air has 53 aircraft in service, data from ACAS shows. These include 11 Airbus A330s eight McDonnell Douglas MD-11F and three McDonnell Douglas MD-90-30. The company's Boeing fleet - three 747-400s, four 747-400 Combis, six 747-BDSFs, three 747-400Fs and 15 777-ERs - total 31 aircraft. It also has options for five Boeing 777-200LRs.
