Q: Can I backtrack?
A: You can backtrack within countries and continents, but you cannot re-enter a continent after leaving it, except: (a) a transit without stopover in Asia on a flight between Europe and SWP or vice versa, (b) a transit without stopover in Asia on a flight between North America and SWP or vice versa, (c) a transit without stopover in North America on a flight between South America and SWP, Asia or Europe or vice versa, (d) a transit without stopover in Europe on a flight between Europe and Ghana or Nigeria or vice versa. Any of these transit without stopover benefits can be taken in either direction (eg. Europe-SWP or SWP-Europe) and either before or after you wish to enter the continent for the second time to use your stopovers there. You can only leave and re-enter the continent of origin once, except for North America where you may have an additional transit without stopover.
