I will fly in internationally to Frankfurt and then to Stuttgart via Deutsche Bahn.
Then after a few days in Stuttgart I have to fly from Stuttgart to Berlin for a short business meeting and then to Munich. I will have my travel bags (say 15 to 18 kilos not too big) with me at Stuttgart but they don't need to do the trip to Berlin. I can travel light and then say fly to Munich where I would want my travel bag.
Is there a way (say) via Deutsche Bahn (or otherwise) where I could drop off my bigger bag at Stuttgart railway station and have them move it to Munich on a train and I can later (say the next day or in 2 days) pick it up at Munich?
Basically it allows me to not drag my heavy bag when not needed and also fly a cabin bags only flight leg (much cheaper).
Any other ideas?
