When you reserve a flight online the airline sends you an email that includes a six-digit, alphanumeric reservation-confirmation-number; this eliminates the need for a paper ticket. The confirmation number allows you to check-in for your flight -- online -- up to 24 hours prior to your scheduled departure time. You have the option of using your ticketless confirmation to check in at a Southwest Airline kiosk at the airport.
