We've definitely gotten somewhere in the thousands from it. This year we are actually switching the companion temporarily to one of our kids, which we've never done before, so that increases the value even more. As other posters have stated, it's hard to exactly quantify, because I've accompanied my husband on trips where I might have otherwise stayed home, and we've taken extra vacations because of the cheap airfare with a CP, but then we have to pay for the vacations.
