I just let a <$200 ticket go without canceling. If UA wants pax to cancel in these situations, it should give us an economic incentive to do so. As it currently stands, there is zero incentive where the fare is less than the change fee (And please no comments about SDC'ing it day after to day until I can get a refund. Not going to play that game, which I view as the type of abuse that could lead to UA ultimately restricting this extremely valuable benefit.)
