Star Alliance
On November 10, 2010, Star Alliance announced that Avianca (and its merger counterpart, TACA) were full members in 2012. Due to Avianca's entry into Star Alliance, it ended its codeshare agreement with Delta Air Lines and began a new codeshare agreement with United Airlines. TACA had been codesharing with United Airlines since 2006. On 21 June 2012, Avianca and TACA were both officially admitted into Star Alliance.
