I have a question. I will be travelling to Cologne this summer and on LH.com, I found out there are 2 option from HKG.

1) You can fly all the way and connect via Munich.
2) You can connect in FRA and take train to Koln station. Here is the confusion. The train number is on a LH number. So what happens to my luggage upon my arrival in FRA? Will I still need to lug it to the Train station myself? Do I collect the train ticket during my checkin in HKG? How does the system work?

Or is it just easier to connect my flight in Munich?

Thanks!
