When I say "save", I'm talking about the difference between non-DD price online and non-DD price at the airport. You're right that my savings rate is less when comparing it to the DD price, but it's still cheaper overall which is what is important to me. I'm not always saving $23/person/segment. Also, there are many times when the DD price and the non-DD price are less than $10 apart. Those are usually shorter flights. I've seen the difference be as low as $1-3 before. Now granted, the CIC charge won't be as high so it will be proportional to the fare, but still cheaper.
