Air France ticket includes TGV, CDG-Lyon, timing?

to get to the train you have to go through immigration and retrieve luggage and go through customs (generally just walking through the door). I cannot imagine that is adequate time. Even on a good day it is rare to get from the plane through immigration in 20 minutes. The walk from the gate to immigration is substantial and then in our experience the lines for immigration have ranged from 15 minutes to 90 minutes and there is no way to deal with that. 22 minutes is IMHO impossible even in the best case scenario. You need to get AF to book you a later train even if it means connections on the train or taking a cab into Paris to Gare de Lyon for a latter trains. The rule of thumb at CDG is 3 hours from ETA to train and 4 hours if taking the train in Paris. This gives a cushion for the normal delays of slightly late plane or an unusually long immigration process. If you are checking luggage -- luggage at CDG can be very very slow but in no case would you have it fast enough to make a 22 minute connection.

If you miss the train on this combo ticket, go into the ticket office inside the SNCF train station at the airport. The clerks will take care of you. To be sure, call Air France and ask them.

In the old days, the luggage would be transferred for you, just like a plane itinerary and AF had its own waiting room in the train station, but I think those days are over, but you could always check to see if any special services still exist.

"22 minutes is IMHO impossible even in the best case scenario. "
The OP has 1 hour and 22 minutes. I'm not sure that is enough time but the good news is that with the "Air + Train" ticket, they will be put at no extra cost on the next available train to Lyon. There is a dedicated desk for travelers with that ticket. I'd just keep my ticket and if there is a delay that affects the arrival get the later train. I mean why change it now when you may not need to.

JHK- to clarify, is the dedicated desk in the train station?

Thanks everyone for the quick replies. I will definitely call air France. We'll only have Carry on. I'm an EU citizen so I might get through the line quicker but that doesn't help if I have to wait for my husband, although I suppose I could heat to the ticket office first if we're going to miss the train. I've looked and there is another one a couple of hours later so as long as those trains don't sell out, we could take the later one. If changing isn't a hassle and it's on Air France to handle it, I'd rather just keep the ticket as it is just in case we do make it. I'll post an update if I get through to Air France.

oh sorry -- obviously misread -- 82 minutes might be makable especially if there isn't checked luggage. there is still a fair chance of missing but I wouldn't worry and just go AF to fix it if the plane is late. When we got re-scheduled on an AF flight because of an equipment change they had already rebooked. I don't know if AF does that at CDG but I wouldn't be surprised. Flights from the US often come in a little early (they pad the schedule to keep their 'on-time' record) so you might even luck out there.

The real issue if if they factor in slow immigration for Americans.

@ Elizabeth, the desk is in the train station, on level 2.

Thanks all, I'm feeling better about the connection, especially knowing there is another train just a couple of hours later. I've done a little checking on youtube (watching videos of people going from Terminal 2E to the train etc) and have looked on SNCF app to see that there are still plenty of seats open on the later train so we should be good.
I tried using whatsapp to connect with Air France, I'm currently in a queue for call back. It's been over 24hrs, but a few hours ago they texted to say I'm still in the queue. If I don't get through this way I will eventually try one of the phone numbers, I just hesitated to use that route first because they say that they charge for phone booking. I know I'm just trying to get some information but they don't make it easy ....
