a few more points ...

1) valid termination points - for the OW Continent RTW's you need to end in the country of origin. I'm not sure if this is true for other RTW's. Also, on a lot of the mileage based RTW and the Continent RTW you can actually have greater than RTW due to the permisability of backtracking.

2) using the segments at a later date - you can definately do this within the maximum stay rules of the fare.

3) refund of fare - in my one experience with such a refund they will actually use the full fare and not any discounted fare. so you will typically not get a lot back unless your used segments are relatively low cost.

4) most RTW's consider the US and Canada to be one country so you could start in Canada and end in the US without problem.

if you really intend on not using the remaining segments first calculate the OW segemnt fares. if you're due a refund (which is pretty unlikely in most cases) go and cancel the ticket. if you're going to end up owing money just do nothing. either use the segments later or dont - the airline isnt going to come after you and make you pay a penalty!
