We have previously shown that the decay of high-energy neutrinos from distant astrophysical sources would be revealed by flavor ratios that deviate strongly from the $$\phi_{\nu_e}:\phi_{\nu_\mu}:\phi_{\nu_\tau} = 1:1:1$$ expected from oscillations alone. Here we show that the deviations are significantly larger when the mixing angle $$\theta_{13}$$ and the CP phase $$\delta$$ are allowed to be nonzero. If neutrinos decay, this could allow measurement of $$\theta_{13}$$ and $$\delta$$ in IceCube and other near-term neutrino telescopes.
