From March 29th, the airline will also launch extra flights to Sydney and a non-stop route to Vienna.
The airline said it is in a position to offer the new flights thanks to falling fuel prices, with the Frankfurt service being increased in frequency to six times a week.
At the same time, China Airlines' flights to New York from Taipei will increase from three to four a week.
The carrier's president Sun Huang-Hsiang explained that the airline's goal for this year is to "boost sales".
"China Airlines is working continuously to expand its network and strengthen its passenger connections, also to solidify Taiwan's role as a hub between mainland China and the world," he said.
From next March, the airline will offer ten flights to Australia each week, offering greater flexibility for Chinese passengers.
On May 20th, China Airlines began new flights to Surabaya, Indonesia's second-largest city.
