I need to change (or cancel) an award r/t for 3 of us; below are all the cost line items. So I'm reading that CANCEL will be cheaper than CHANGE, in that the $44.40 last line item will be held back, instead of a $100 change fee? Cancel is going to be easier as we're now moving to different flights for all 3 of us, and reward point costs haven't increased since 12/2024 booking. Thanks!
