Taiwanese carrier China Airlines plans to raise frequencies of its services to Bangkok and Osaka.
It will raise the frequency of its Taipei Taoyuan-Bangkok service from thrice to four times daily starting 31 March, says an airline official.
The frequency of its Kaohsiung-Osaka Kansai service will also increase from twice to five times weekly on 1 July.
China Airlines will use Boeing 737-800 aircraft on the additional services.
In addition, the carrier will halve its Taipei Taoyuan-Koror service to twice weekly, from 19 February, adds the official.
Koror is the former capital of Palau, a Pacific island state.
