Frankfurt to paris train

I just checked the German Rail site, www.bahn.de, and didn't find a 12:02 departure time from Frankfurt(M)Flughafen Fernbf (the full name of the station).

I found departure times at 11:54 and 12:54 with connections in Karlsruhe.

If your plane is on time, you'll probably be able to catch the 11:54 train. (But don't count on it.) If you want to book in advance to get a discount fare, make it the 12:54 train. Discount fare tickets are for a specific departure date and time. They are non-exchangeable and non-refundable. If your plane is late, you'll be out the price of the ticket.

Frankfurt Flug FE = Frankfurt Flughafen Fernbahnhof. Fern is the German word for "Far" or long distance trains, not because the station is so far out, although it is.

There are two Bahnhofs (technically Bahnhöfe) at the Frankfurt airport. The Regionalbahnhof is close in, under the building across the access road from Terminal 1 of FRA. You get to it by going down steps, or elevators, just inside the outside, window wall of the great hall of Terminal 1. There will be signs, some of them probably with the green circle, white 'S' indicating an S-Bahn station.

The Fernbahnhof is farther out, on the other side, across the Autobahn, of that building across the road from Terminal 1. You get to it by going up to the 2nd floor mezzanine of the great hall, on the left hand side of the hall and across the pedestrian bridge over the access road, then through the 2nd floor of that building and out a hallway (actually an enclosed bridge over the Autobahn). I'd guess it takes about 10 minutes. Again, there will be signs.

If you fly in on an American flag carrier, you might end up at Terminal 2. You can get from there to Terminal 1 either with the shuttle bus that leaves from in front of Terminal 2 every 10 minutes or by going up to the roof of Terminal 2 and taking the "Skyline" people mover over to the roof of Terminal 1.
