You're right...Air Berlin does not serve Frankfurt directly from Paris....only through a third city, which negates any price break or time savings. There's not much time savings anyway, since the time out to CDG or Orly, plus security, makes the trip longer than by train. I agree with Andreas....the new high speed train link between Paris Est and Frankfurt is the best...4.5 hours downtown to downtown. SNCF and Die Bahn both run trains on this new service...check with each on-line to see if there are any deals. However, if you're travelling in July, most of the cheaper tickets may already be gone...so if you find something for $122 USD, take it!
