Future expansion centers around the addition of "Connecting Partners," subsidiaries or partners of alliance members which will add connectivity to the alliance without becoming full members. Avianca Brasil joined in this way on 22 July 2015, bringing the alliance back into the Brazilian market partially filling the void left by TAM. South African Airways' low-cost subsidiary, Mango, was initially announced to join as a Connecting Partner in Q3 2016 but has since been delayed. Juneyao Airlines, which codeshares with Shenzhen Airlines, joined as a Connecting Partner on 23 May 2017. Thai Smile, subsidiary of Thai Airways, will join as a Connecting Partner in 2020. On 20 August 2019, Star Alliance announced affiliate member Avianca Brasil's exit from the alliance from 1 September 2019. The departure, however, won't affect Avianca's membership. On 30 September 2019, Adria Airways ceased operations, and the airline exited the alliance on 2 October 2019.
