Mundane question:
I am contemplating a self-built connection from Germanwings (T1) to Flybe (T3). Is it possible to stay airside when connecting between the two terminals if one only has handluggage and is already checked-in - or is it impossible because of a lack of passport control airside between the two terminals ? Connecting time would be a rather tight 90 minutes, but as the Germanwings flights would be the first of the day out of CGN with little risk of delay, I might take the risk if a smooth connection is possible at the MAN end.
