Carol.....as I recall, there are different lines depending on what you need to do. I seem to remember an area with kiosks where you could print boarding passes (whether you already had them or not), pay for your checked bags and then drop them off in the same area. Then there was another line if you needed anything else. For example, I had to go through the longer, other line because I had overnighted in Miami and had to show my payment receipts to avoid having to pay for checked luggage twice. I would assume it is still the same.
