Assuming you can't set it at design time, this is a fairly common problem, and there are several ways to fix it, but I need to know a little more. Does your application use a database or something like that? Does the application keep track of multiple bookings, or only one?

The solution is that the value of the checkbox needs to be stored somewhere outside the program. If you use an external database to store information, you can add a field to it. If you aren't using any external files yet you have at least three options.

1. You can create a file to store the checkbox state and read the file every time the application opens. If you only handle one ticket at a time, you don't even need to put anything meaningful in the file. Just create it if the box is checked. Then when the application starts, check to see if that file exists. If it does, have the application check the checkbox. This would even work if you handle multiple tickets. Just create files as needed with the ticket number as the filename. You would need to clean those files up every now and then, though, to get rid of ones that are no longer needed.
2. Basically the same, but use a standard .ini file.
3. Basically the same, but store the value in the registry. It's easier than you think, and you don't need to worry about the file accidently being deleted.
