The checkin kiosks are great and so very easy to use. As opposed to standing in line forever you walk up to a machine that looks sort of like an ATM. You put in a major credit card. You are not billed for anything, and it doesn't have to be the card you used to purchase the ticket. They only use the card to check your identity. Then the machine asks you questions (have you left you bags unattended, did anyone ask you to carry anything...the normal security questions) then it asks you how many bags you are checking. It is all touch screen and so very simple. It prints out the boarding pass, and you walk up to a special line for checking your bags. They weigh them and you may have to show the person your license along with the boarding pass (extra security). The kiosk will not bypass your getting randomly chosen for having your checked baggage security checked. The machine will not give you a boarding pass, and ask you to step up to the kiosk baggage check line for the quick security check, and then they give you the boarding pass. I have used this on both Delta and ATA. I am sure the other airlines have similar machines.
