CDG T1 to T2 airside connection question
I’m flying in to CDG T1 on QR and connecting to T2 for a BA flight to LHR.
Hand baggage only. Separate tickets but will have my BA boarding pass.
Can I get the airside transfer bus or do I have to clear immigration, go landside and transfer to T2?
Appreciate help so I can work out which flight to book back to LHR.
