Hello @lgritli
Thank you for your query.
An extension of the subscription is not possible. To enable us to check your case, please contact our Railservice on 0848 44 66 88 (CHF 0.08/min) or go to an SBB railway counter.
Currently, there are still ongoing votes on how exactly subscriptions, including the GA, customers will be compensated due to the current situation. You can find the latest information at: https://www.allianceswisspass.ch/de/Themen/TarifeVorschriften/Coronavirus.
I wish you a nice day.
Kind regards, AferditaS
