Lee Jun-ki in Switzerland ... there is always more!

Where the heck did this picture suddenly come from?! ROFL. 

I got it from the Lee Jun Ki / BG Family page on Facebook and I see that someone at Mandarina Duck (the bag company) got to it sooner than everybody else ... Nice way of creating an ad!
Lee Jun-ki is about to board a ZVV S-Bahn. ZVV stands for Zürcher VerkehrsVerbund, which is the local transportation organisation. A S-Bahn is a local train (they run in the whole Canton of Zurich). Joongi was most likely taking the train to go from the airport to Zurich main station (this is his look from Seoul airport, on 22 November, not when he returned).

Wow, Joongi, you used our public transport! That's so cool!
