Not even 15 years old, and LH starts phasing out the 733? On the other hand, I found a pic of D-ABYM, the oldest aircraft in the whole Lufthansa fleet - 23 years old and probably in service with LH for some more years:

Look, D-ABYM seems to smile while taking off, saying "Hey, Giessen, you already want to leave? Look at me, I'm Schleswig-Holstein, and I will be flying until hell freezes!"
Seriously, LH should really phase out the 742 before getting rid of the beautiful 733!
