Hi Arno, thanks for the clarification on the Luzerne route.
As for crowded trains on weekends or weekdays from Zurich airport to Grindelwald via Luzern, hopefully regular travellers to the region can shed some light. I will also check out the transport link in advance, for weekends to see how crowded it gets to have an idea.
We will have to make a judgement call whether to fly into Zurich airport on a weekday or weekend when we book our tickets. The flight usually lands around 8am. :). Still have plenty of time to plan as its for next June although the Air Superdeal fares come out 6-8mths in advance.
