In this talk I discuss neutrino oscillations with different oscillation parameters for neutrinos and antineutrinos. According to the CPT theorem neutrinos and antineutrinos should behave the same, except for effects of the CP-phase $\delta$. I discuss the bounds that can be put on the differences between neutrino and antineutrino parameters from current neutrino and antineutrino data. I also discuss prospects for future experiments, and in particular some interesting scenarios that arise in the context of CPT violation, such as impostor solutions. I also discuss mimicking effects between CPT-violating neutrino oscillations and non standard neutrino interactions.
