The scripted comedy cable network will bring back the Ice Cube and Matt Alvarez-produced series after its initial 10-episode run this summer.
The massive reorder was triggered as part of the show's increasingly common dealmaking structure, a system pioneered by Tyler Perry and Debmar Mercury's comedies on the network.
" 'Are We There Yet?' attracts a young, diverse audience, making it an especially good fit for our Wednesday night slate of original sitcoms," said Michael Wright, head of programming at TBS.
Since its June 2 premiere, the comedy has averaged 2.8 million viewers and 1.5 million adults 18-49.
