Sorry for not responding to your PM on this topic, I was in China for two weeks and mostly offline (also thanks to the great firewall).
Some recommendations on TAs in Germany are here:

I personally would
rcs85551s agency Skytravelagent. Note that they are very smart optimising your routing etc to maximise miles, but for short hops and simple economy tickets you are better off using the many OTA offerings out there via kayak. The OTAs usually outbid themselves to get to the number 1 position in kayak or skyscanner type search engines and you can save 20-30€ per simple return.
