I will be arriving in CDG-2E off an AF/J flight and am due to connect 6 hours later from the same terminal on a JL/C flight. Does anyone know if I could access the CX lounge in terminal 2A without going through too many hoops other than a transfer bus?

More important, is the CX/F lounge in 2A much better than the AF/J lounge in 2E (JL seems to contract with AF for lounge usage)?
