In which episode does Korra first airbend?

Korra first airbends in “Endgame,” the twelfth and final episode of Book One: Air. During the climactic confrontation with Amon, she uses airbending to save Mako and force Amon through a window.

Before this moment, Korra can bend water, earth, and fire but struggles with airbending. Tenzin’s lessons repeatedly expose her difficulty with the discipline’s emphasis on evasiveness, humility, and spiritual openness. Her breakthrough comes under extreme emotional pressure rather than during formal training.

The scene is easy to confuse with “A Leaf in the Wind,” where Korra begins learning airbending principles, or with “Welcome to Republic City,” where she arrives to study under Tenzin. Neither episode shows her successfully airbending. After unlocking the element, Korra becomes a fully realized Avatar once Aang restores her other bending abilities and connects her to her spiritual self.
