I will be travelling through CDG Paris Airport to my next Camino. I have done CDG Paris before with transfers from Terminal 2E to 2F with no problem. My next trip has me transfer from Terminal 2E to 2G for my flight to Biarritz. I have learnt I have to go outside of Terminal 2E to catch a shuttle to go to Terminal 2G. Anyone with more info. on this please advise. Thank you.
