Acceleration and deceleration of one-dimensional and two-dimensional obliquely incident Airy beams are investigated theoretically and numerically. Onedimensional Airy beams with given initial velocities propagate along parabolic trajectories. However, the beams will undergo deceleration and then acceleration if the initial velocity is in the opposite direction to the acceleration. In the opposite case, the beams will only accelerate during propagation. Two-dimensional tilted Airy beams are treated as products of two 1D Airy beams with initial velocities. Such accelerating and decelerating properties due to initial velocities can be effectively controlled by small angles of incidence.
