Their model is based on selling bulk (60-80%) of capacity to tour operators, so they know months in advance how their flights are booked. Of course, the prices German TTOOs pay are much lower than if you boo direct with Condor, but you cannot buy just the flight ticket with TTOO it must be packaged.
Anyway, after they know their main loads, they will release the remainder of tickets for sale to public via GDS, travel agents, and their own website/call center.
The LCC designation comes more from airline economics and how they work economically internally than from a product you receive from them. JetBlue and Virgin America are LCCs yet they offer better service than legacy carriers.
Even within LCC world (which again has more to do with internal airline economics rather than a hard or soft product they offer) there is a subdivision, now basically "hybrid LCCs" such as Jetblue and VA, and UltraLCC (ULCC) such as Spirit, frontier, Allegiant. With HLCCs you do not see much difference in rad and soft product between them and legacies, with the exception of missing business/first class, while with ULCCs you see a substantial difference in both hard and soft product (tighter seats, no onboard service, basically everything is for purchase such as priority boarding, seat assignments, meals, drinks, etc.).
