  We reinforce the observations of almost stable scattering in nonintegrable
models and show that $\mathcal{PT}$-symmetry can be used as a guiding principle
to select relevant systems also when it comes to integrability properties. We
show that the presence of unbroken $\mathcal{PT}$-symmetry in classical field
theories produces quasi-integrable excitations with asymptotically conserved
charges.
