In general, there is no expiation for a traveler's fast and he must only make up for it. However, in some circumstances, a traveler must make up for his fast. For example, if a traveler breaks his fast before reaching the prescribed limit, he must make up for his fast. The expiation for a traveler's fast is to feed 60 poor people or fast for 60 days. Keep in mind that the 60 days of fasting in the first month and one day of it must be uninterrupted and consecutive, but the remaining days can be in different months.
