Star Alliance saw a tumultuous 2012–13, starting with two key departures but ending with a major move into Latin America. In Europe, Spanair ceased operations, and BMI left after being acquired by International Airlines Group (IAG), the parent company of Oneworld members Iberia and British Airways. BMI was integrated into British Airways. In North America, Continental merged with United Airlines, reducing Star's membership further, even if it effectively stayed in the alliance after the merger. On 21 June, though, Avianca, TACA Airlines and Copa Airlines joined, massively increasing the alliance's Latin American presence. In November, Blue1 left after becoming an affiliate of parent Scandinavian Airlines. and Shenzhen Airlines joined, augmenting Air China's Chinese network. Taiwanese carrier EVA Air then joined on 18 June 2013, and after TACA's integration into Avianca, the alliance grew to 28 members, making it the largest of the three major airline alliances. On 13 December, Air India was again invited to begin an integration process with Star Alliance and joined the alliance on 3 July 2014.
