By May 2007, Star Alliance's 10th anniversary, its members had a combined 16,000 daily departures to 855 destinations in 155 countries and served 406 million passengers annually.
The alliance introduced Biosphere Connections, a partnership with UNESCO, the International Union for Conservation of Nature (IUCN), and the Ramsar Convention On Wetlands to promote environmental sustainability.
At the time, it was rumored that the switch was Continental's first move in a planned United Airlines-Continental merge.
The next airline to join was All Nippon Airways (ANA), the group's second Asian airline, on 15 October 1999.
In 2000, the alliance also opened its first three business centers (in Los Angeles, Frankfurt, and Bangkok) and announced the formation of an Alliance Management Team (AMT), the partnership's executive body.
According to alliance CEO Jaan Albrecht, "Bringing Continental Airlines into Star Alliance has been a truly unique experience.
This is the first time an airline has moved directly from one alliance to another and I would like to thank all those involved in ensuring a smooth switch".
