Yup, and don't have to pay for their flight training until they get a job on the mainline. Lufthansa always loaned out its cadets to other airlines (even direct competitors) if they didn't have enough demand to employ them directly. When the demand is there or their number is up they will return to Lufthansa. The waiting list is quite long at the moment and every cadet will have to wait quite a few years, better to fly elsewhere and get some experience (and some money of course too).
Others work in the cabin at lufthansa to wait out their time, same as AL did.
