I just purchased a Lucern to Paris train ticket on the SBB website. The Basel to Paris segment has details on it regarding Train #, times etc while the Lucern to Basel only has the date on it and is called a "Add-on" ticket. I'm assuming this means that this portion is open to me for use anytime on the day. It does say it is only valid with global price offer which I take means it's valid with the other ticket only. Can someone confirm this?
Thanks
