Avion: Your assertion that TWA can still fly from Paris to Munich is plain wrong. All these route authorities were lost, when France cancelled the bilateral aviation treaty with the U.S. in '92. U.S. airlines couldnt fly these routes, even if they didn't offer local service, i.e. CDG-MUC.
Currently, U.S. carriers only have beyond-rights from Paris to TLV and CAI, and this even includes local traffic rights. The authority is restricted to 11 weekly flights, and no more than 7 weekly flights are allowed to each of the stations. TWA recently applied for 7 weekly frequencies on the CDG-TLV route, and expects to launch service later this year. This leaves four weekly frequencies to CAI, which are currently not used by any U.S. carrier. TWA may pick those up, too.
Another exception exists for freight airlines. This enabled Fedex to set up a European hub at CDG.
Eventually, when an open-skies agreement between the U.S. and France has been implemented, U.S. airlines will have blanket authority to operate an unlimited number of flights to France AND beyond, however still with no local traffic rights. This won't happen until 2003, though - unless Air France puts some pressure on the French government, so speed it up. They may choose to do this, because the U.S. government will refuse the DL/AF alliance antitrust immunity, unless an open-skies agreement is fully implemented.
