I will arrive on Sunday at 7am from PTP with Air Caraibes and have until 1pm to self transfer for a Transavia flight to BER in Terminal 3.

Is there any lounge I can use (either cash or priority pass). I see there is a PP lounge in Terminal 1 but I’m not sure if it is possible to walk airside between terminal 1 and 3.
there also seems to be an AirFrance lounge in Terminal 3 but they don’t seem to accept Transavia Passengers for cash. Any advice would be very appreciated.
