It is Allah's mercy that He has made travel easy for us all. If someone is travelling they have the concession to break their fast and they can also shorten their Salaah.
It is should be noted that combining prayers is not restricted to travelling. You can join prayers together during storms, heavy rains, snow storms. It is allowed even when someone is going through hardship and they cannot pray on time.
