I'm planning on buying the half fare card combined with the Berner Oberland pass for the days when we are in the Jungfrau area. We are going to Switzerland for a week in August. One night in Lucerne, 4 nights in Lauterbrunnen, and two nights in Basel. I have the SBB app in my phone ready to go. I have some questions about purchasing logistics. We are two adults and one teenager.
-Is the half fare card valid for a month?
-Can I purchase the half fare card ahead of time and then start it's validation when I arrive in Switzerland?
-I am planning on purchasing the Berner Oberland pass using my half fare card because I believe that makes the cost of the Berner Oberland pass half the original price. Am I understanding that correctly?
-I can purchase the Berner Oberland pass when I arrive in Switzerland?
