We will be traveling from Geneva to Colmar in early August, following a Tour du Mont Blanc hike with REI Adventures. They provide the transfer from Chamonix to Geneva Airport in the morning and said we could book onward travel “anytime after 11 am”. We will use our Swiss Passes to go to Basel and then pay for the train from there to Colmar.
Looking at schedules on SBB, I found an 11:05 train from the airport to Basel, with one change at Biel. This train connects with a French TER train to Colmar departing at 14:21, arriving in Colmar around 15:05 with no changes. So I bought the tickets from Trainline.eu for the 14:21 TER and have them printed out.
I considered the possibility that they were talking about a flight after 11 :00 am, and by train we could depart earlier, but I did not want to assume that. Now we have received our full details for arrival and departure, and it turns out we will depart Chamonix at 7:30 am and get to Geneva airport about an hour later, so we certainly can start our Colmar journey about two hours earlier.
My question is, can we use the tickets we have on an earlier TER train? The tickets are “Senior”, non-exchangeable, and say they are valid only on regional TER trains for the selected date of travel. Then it says “valid during Blue “off=peak”) hours.” Am I correct in thinking we can safely board an earlier TER train than the 14:21 I booked, as long as it is off-peak?
Thanks for your help.
