Still having trouble.

I can with the advanced flight option get to the "reserve a ticket page", and then click on the "search for available flights" option, which will get me to the page with the available flights, with the number of seats available with each fare code (business and economy classes).

I do not know how to go on to select the flights, as part of the reservation steps (ie how do I confirm a booking?) - obviously, I need to be able to go through these steps, before I can see the "seat pick" option.

Are there a completely different set of steps for reserving/booking a ticket compared to just seeing the available number of seats at each fare code? Can one go through these steps, view the available seat selction, without actually purchasing a ticket?
