I am flying in to CDG very soon and need to transfer as cheaply as possible to Beauvais airport to meet a Ryanair flight. I am having a difficult time finding out how to do it less than 170 euros. Can anyone help?
Welcome to the world of low fare airlines' false economy.
There is a bus running directly from Paris (Porte Maillot) to Beauvais. It leaves around 3 hrs before flight time and costs €13. You can use the rail system in Paris to get from CDG to Porte Maillot. From CDG take the RER B line to Chatelet-Les Halles, then the Metro 1 line to Porte Maillot. I'm not sure of the fare, but it has to be only a few Euro.
Here's a link to a shuttle service that runs between the two airports. http://www.capitolshuttle.com/?gclid=COmcmay3iJMCFSkvagodY3euew Looks like 60Euro per person.
The RER & Metro route from CDG to Porte Maillot costs 8.20€.

Thanks for all the help!
