I purchased a Snow’n’Rail combo for Jungfrau ski region for 6 days.
The train travel is on 23/03/2026 and 30/03/2026
On the email of the ticket issued the ski pass validity is 23/03/2026 - 28/03/2026 (6 Days).
But I will arrive to Wengen at 8pm on the 23/03/2026. How can I change the ski pass validity to 24/03/2026 - 29/03/2026 (6 Days) to make sensible use of the 6 days?
Thank you for the advice!
