How about this: charge for carry ON bags: One bag free for all, $25 per bag for any additional. Fees go to TSA. Either checked bags are free, or the fees go to the TSA, since they have to pick through those also.

If the airlines are making "billions" off of check bag fees and are doing nothing additional for them, the TSA should get the money as a "user fee." Increase in TSA budget comes from flyers, not non-flyers. Seems fair to me.
