We propose a strategy to control the propagations of Airy beams in photonic lattices relying on optical Bloch oscillations (BOs). We predict the existence of optical BOs of Airy beams in photonic lattices with a refractive index ramp. It is found that Airy beams undergoing optical BOs show an alternatively switched concave and convex trajectory as well as a periodical revival of beam profiles. Moreover, the reconfigurability of the photonic lattices enables us to control optical BOs of Airy beams by varying the transverse index gradient or the orientation of the lattice, which offers opportunities to steer the Airy beam to a specific output channel.
