Cuando yo hacía un viaje, yo tomaba una maleta grande
Explanation:
Imperfect preterit refers to an action that has occurred in the past, but without clearly defined temporal limits. This means that we are not clear when these travels happened or even if they are still happening to this day. In Spanish it's often used when two past actions occurred simultaneously.
