I have a reservation to arrive at CDG on a Friday in May this year and hope to depart soon after for Strasbourg by TGV and know a reservation is required. It is sometimes slow and difficult to get from the plane through immigration and customs. I should have 2 hours between arrival and departure of the TGV (morning). There is another 2 hrs 23 minutes later. Since arrival is on a Friday morning I expect the TGV demand to be high and am watching it now. If I were sure of the trip I could make a reservation now but plan to wait about another month.
One strategy is to book the earlier departure knowing that if the plane flies at all I could make the later TGV. Another is just the opposite, i.e. book the earlier thinking that if it becomes clear that I can’t catch it in time I could possibly change the reservation to the later TGV. My wife will be waiting at CDG and will know the status of the flight and could make the change if it is clear we wont make the early TGV. She will be at the TGV station in early morning and if that’s the way to make the change, she could do it there.
The problem is that I cannot get a straight answer about the ability or process to make a TGV reservation change. I’d appreciate info about that.
Also, any advice about the plan in general is welcome. (I’ve written to the Eurail office and got a non answer saying that reservation changes are controlled by the operating rail company, and I wrote SNCF and got a confusing answer.) Another confusing thing is that the reservation page very often reads “seat availability unknown” even for a train leaving that day even when a reservation can be purchased. How can that be?
Elsewhere in this forum I read some very interesting info regarding TGV and ICE reservations from Germany through France and one contributor suggested trying the Belgian rail operator. This TGV through CDG originates in Belgium, I think, so maybe I could get a straighter answer from them.
