So I know when I used points to book travel and I change the flight I get a refund back of the difference. But I never cancelled a flight outright. IF I were to book and cancel, do I get the fund back or a voucher to use them within a year? OR nothing at all? Just curious cause if I book my January and cannot go cause wife is not feeling well or god forbid any other issues with pregnancy arise (bed rest etc...) Obviously I would cancel either way but just curious.
