I spoke with a bride this week that is charging all of her expenses to a credit card that gives frequent-flier miles - I thought it was a neat idea to get a little extra “bonus” this way.  I have an aunt that did this with my cousin’s college tuition, but I never thought about it in conjunction with wedding planning.  Of course, I would only recommend doing this if you have the money to pay the bill when it comes in - I would discourage charging above your budget and starting your new married life in debt.
