$200 per segment in Europe is fairly inexpensive for a 'full service' carrier and like U.S. airlines these low(er) fares have all sorts of restrictions.
Did you get a doctor's letter and contact LH before the flight? @:-)
My experiences with LH have been very good, but I have never "no-showed." I have bought some discounted flights that had change penalties, and was able to change them and in a couple cases have had the penalty waived. Then again I have SEN status and try to be polite.
