Star Alliance

Following this string of expansions, 2014 opened with two major departures through mergers. First, Brazilian carrier TAM Airlines merged with LAN Airlines to become LATAM Airlines Group, leaving the alliance without a presence in the world's fifth-largest country. Next, US Airways completed its merger with American Airlines and also left the alliance. Both parent companies stayed with Oneworld. On 24 June, though, the alliance finally approved Air India which joined on 11 July, leaving the alliance at 27 members, where it stands today.
