Hello Helmuth
Yes, I am also married to a German citizen. (lived there many years...as a soldier,student, and post-grad) I also majored in German Studies in college, so the language requirement for CityLine is not a problem...keep in mind, you must be fluent in reading,speaking, and writing. Also, you must be an EU citizen, or, I'm told they might make an exception to this if you hold a permanent visa (EU green card) and work permit. You may not be older than 35.
And, as of recently, the CityLine ab-initio training program has seperated from the LH flight school (LFT) and is working on new logistics, such as where, when, and how much.
This is due to LH's desperate need of pilots, which demands full capacity of their flight school. (they should nix some of their eyesight and age requirements instead!)
Anyways, let me know if you have any questions, I would be happy to help out if I can.
Ciao!
