  • What some people have discovered is that c to a to b, and later b to a to c, can be cheaper than a to b and back, even when the a to b legs are on the exact same flights. (This is most common when a and c are on different sides of the Canadian border - YYZ-YVR-SEA and back is cheaper than YYZ-YVR a lot of the time.) So you get yourself to c somehow, and then start your trip.
