A simple Regge pole model for $K\pi$ scattering explains the large $e^{i
\delta}$ between isospin amplitudes which is observed at the D meson mass
($\delta \approx \pi/2$). It predicts $\delta \approx 14^{\circ}-
20^{\circ}$ at the B mass. Implications for ($B \to K \pi$) decays and
extensions of the model to other two-body decay channels are briefly discussed.
