The 'Tickets' tab will show you a list of every ticket which has been won by a player. When creating a tournament, you can choose the option 'Satellite for' and if the player finishes in a position that awards a ticket then the ticket will be shown here.
Here you will see this player has a ticket for the 'Progressive KO'. The ticket doesn't have an expiration date and it has not yet been used. You can double click on the ticket to see and edit some information regarding it.
Here you can choose whether the player has the option to cashout the value of the ticket by hitting 'Allow ticket cashout'.
