My wife and I will be traveling to Biarritz, France in April. We booked the flight to Paris some months ago before final travel plans, in France, were finalized. Our transit leg, from CDG to BIQ is separately ticketed with Air France. We won't have checked luggage (carryon only).

The Air France leg to BIQ is now booked, but it seems we're unable to get a boarding pass before we leave the US. Hence my question. Can you obtain a boarding pass (airside) from Air France on arrival at CDG and simply transfer by shuttle to T2G? Or do you have to exit the airport and use the landside shuttle to T2G and check-in there with Air France?

Thank you!
