The spouse who earns frequent flyer miles or loyalty points may feel emotionally attached to those miles or points since they are perceived as a reward or a prize for the travel and endless nights away from home.  If earned during the marriage; from the date of marriage to the date of separation; they are marital property and can be subject to equitable distribution.  Assigning a fair market cash value to the miles and points could be extremely difficult since the “value” can vary depending on where and when the travel or use will occur. Some providers will divide them into separate accounts under each spouse’s name, but it could be costly.
