Corrected entry: In Superman The Movie. Marlon Brando banished the three (Zod,Ursa,and Non) to the Phantom Zone. Meanwhile Kal-El is launched to earth. Why does Kal-El age roughly 5 years during his journey,and then 13 more as a teenager,then 12 more. The three Kryptonian prisoners didn't age.

Correction: This is a question, not a mistake. The properties of the phantom zone are never fully explained in the films. But dialogue in both films explains that the villains were sentenced "for all eternity." Which suggests that time has no meaning in the phantom zone... so they wouldn't age.
