In this paper, Lorentz Invariance Violation (LIV) is considered in the calculations of photon propagation in the Universe. LIV is considered only in the photon sector and the mean free path of the \gamma \gamma -> e- e+ interaction is calculated. The corresponding photon horizon including LIV effects is used to predict major changes in the propagation of photons with energy above 10 16 eV. The GZK photon flux on Earth is calculated and compared to the Lorentz invariant scenario. It is shown that upper limits on the photon flux at the highest energies can set limits on the LIV coefficients.
