  We follow up on the analysis of Mecozzi and Bellini (arXiv:1110:1253v1) where
they showed, in principle, the possibility of superluminal propagation of
neutrinos, as indicated by the recent OPERA result. We refine the analysis by
introducing wave packets for the superposition of energy eigenstates and
discuss the implications of their results with realistic values for the mixing
and mass parameters in a full three neutrino mixing scenario. Our analysis
shows the possibility of superluminal propagation of neutrino flavour in a very
narrow range of neutrino parameter space. Simultaneously this reduces the
number of observable events drastically. Therefore, the OPERA result cannot be
explained in this frame-work.
