Paying for Prems w/ AmEx
 

Is this possible?

sure, as far as I know. Why wouldn't it be? They show AMEX as a possibility in the section where you are asked to pay, so they must accept it.

You just can't use it to get tickets automatically at a machine as it doesn't have a chip, that's all (or retrieve them, but if you have a pREM and print it, that shouldn't be an issue anyway).

I've never used anything BUT Amex to purchase PREMs or any other SNCF tickets.

Yes. Did that last year.

Thank you everyone, I think I was reading the bit about tix machines. Now I just have to print them out and then book 7 more tix over the course of the next 10 days. (Don't ask--people are arriving and departing on different days and I'm in charge of the TGV tix) Should be a pro by the time I'm done!!!!

BTW any issues re printing as I will be emailing tix to others so they can print.

It was last summer but I seem to recall I had a choice of PDF or
HTML format to print out the tickets.

It might be an idea for you to download them once purchased, email to the others and keep a copy just in case...
