I’ll be flying into Basel this December with onward travel to Lauterbrunnen. I know a saver day pass will allow me to use any train from Basel to Lauterbrunnen for the day of purchase as that covers the GA travel card area. My question is around getting from Basel Airport to the train station. I understand I would need the B50 bus. Is this route covered by the GA travel card area and included in the saver day pass or would I need a separate ticket? Thanks.
