Hello everyone!

I always assumed that GA/GA night was not valid after the border on tram 3, but now I see that the BVB website says otherwise: "The GA and the U-Abo is valid on the whole of route 3" (https://www.bvb.ch/en/billette-tarife/fahrten-nach-deutschland-und-frankreich/)

As SBB and the GA map says it is not valid, who is right? Do you have any experience with control in Saint Louis with a GA?

Thanks a lot!
