Divorce can feel a lot like air travel—riddled with turbulence, unexpected delays and the occasional baggage mishap. Amidst all the emotional strain, division of property, and custody arrangements, there is a lesser-known battleground that divorcing couples rarely think about until it's too late: frequent flyer miles. Even in non-divorce cases, rows over frequent flyer miles can lead to some rather intense court battles. So, given the high emotions and potentially high costs associated with these disputes, it is key that spouses work together to properly divide this marital asset.
