Well, I thought you meant something else with time... You know, the passing of time, duration, the past, the present, the future. With time you meant hours/minutes form, e.g. 23:12...
Actually, it would remain the same, not stop really..., if the plane could continuously move with fixed speed, then days would pass, but time would remain the same, through the whole flight.
edit: Teleporting does not include the execution of the route, but transport by dematerializing at one point and assembling at another.
