I have a TGV train booked from Gare Montparnasse to Rennes. There is 12 days left to travel. Now I want to change the booking from CDG airport to Rennes on that same day i.e., I want to change the boarding station.

Do I need to pay charge for this change and if so, how much ?

    How did you book it? Can you look it up online? – Relaxed Aug 19 at 9:39
  • @Relaxed, i have booked online and paid – M. A. SARKAR Aug 19 at 13:10
  • If you booked it directly from SNCF, you should be able to modify it yourself on oui.sncf/monvoyage/recherche using its reference number. – Relaxed Aug 19 at 13:39

It depends on your fare, some TGV tickets can be changed, some can be changed for a small fee up to two days before travel, others yet cannot or not without a hefty fee. If your fare allows it and seats are available, it could be possible to change the date and time without additional fee.

Additionally, there are very few TGV from CDG to Rennes (one a day, I think), perhaps a handful of possible TGV connections. Most of the time, the train connections shown use local transit (RER) to reach Montparnasse. If you want to do that, you could also keep your current ticket and just buy a local transit ticket separately. Do budget some additional time to navigate the Paris local transportation network (especially if you have a lot of luggage).

But @MaxJasper's suggestion is also well worth considering: Le Bus Direct is somewhat more expensive but a lot less hassle in this case as it would bring you directly to the train station from the airport without the need to figure out a local transit connection.

The airport website provides additional info on the various ways to reach Paris from CDG, with links to buy tickets when available.

Don't waste your time and a lot of money to change your TGV ticket. At CDG jump on Les BusDirect #4 for 17€ and get off at Montparnass Gare and board your TGV to Rennes without hassle. Bon voyages.

  • (+1) Great option, I missed line 4 when I looked up the airport page earlier! – Relaxed Aug 19 at 16:16
  • My sister used to live at Montparnasse, I've taken that bus many times and highly recommend it as the least hassle – user61942 Aug 19 at 23:12
  • I think it's more commonly known as Gare Montparnasse. – Strawberry Aug 20 at 17:27

The train from Montparnasse to Rennes and the train from Charles de Gaulle to Rennes are different trains, so you are looking to change the booking entirely.

Depending on the ticket type you booked, you may be able to get a refund on the original ticket and book a new one.

If it is "Modifiable sous conditions", then you should be able to get a refund (minus €5) until the day before departure.
