Our flight from JFK is scheduled to land at 6:55 a.m. on 6/20. Our plan is to take the train to Avignon that morning when we land as we're staying in Saignon. (We don't want to fly down as we're train lovers.) My question is, how much time should we allow between scheduled landing and train departure from CDG? We'll need to go through customs and get a bag.
(Also, I've only ever taken the TGV from Barcelona to Paris in the past, I can't seem to figure out why some train time are already available for purchase but most say, "you're too early to book!")
