Oneworld Alliance, the most comprehensive and selective international airline alliance, was formally established on February 1, 1999, and was originally headquartered in Vancouver, Canada, before relocating to New York. Its member airlines and their affiliates cooperate on a wide range of issues including flight times, ticketing, code-sharing, passenger transfers, frequent flyer programs, airport VIPs and expense reduction, and in April 2005, oneworld became the first airline alliance in the world to implement e-ticket interoperability arrangements between its member airlines when it completed the process.
