Schengen to Asia transit: FRA vs ZRH
I am asking this question on behalf of my best friend, who has traveled quite a lot, but is not good at directions outside the US. He will travel from Berlin to Seoul via HKG.
There is an itinerary on LH (TXL to FRA or ZRH) and then CX (to HKG and then ICN) that looks ok to him.
However, there is a dilemma: ideally, transit via ZRH is better than FRA (the worst major airport I have been to). Yet, the transit time via ZRH is only 1 hr 10 min, whereas for FRA is 1 hr 50 min. Which one is better? The transit time in FRA is longer, but FRA can be a zoo, if he is unlucky. He does have e-passport access for German immigration, but my prior experience shows that many a time, the stupid machines don't work.
What do you recommend?
Also, even in FRA, does he have to go through security again? Thanks.
