Air China and Air Berlin launched interline electronic ticketing in late April, making Air Berlin Air China's 100th IET partner worldwide.

Since Cathay Pacific Airways became Air China's first IET partner in April 2006, Air China has implemented interline electronic ticketing with all Star Alliance members and its major interline partners in the Americas, Europe, Asia, and Oceania.

Travelers with valid e-tickets from Air China can take any flight operated by its interline partners worldwide.
