Effoh,
Thanks for posting this info. I am JMC'ing with the family LGW-TFS (JMC772K) on 7th Sept, and believe this to be a 320 rotation.
I have several hundred hours as pax (and current PPL/IMC 230hrs), but have never yet flown in a "minibus".
On the basis that if you ask nicely, you might get, I am going to give this a try.
(Last J/S was about 9 months ago - night departure from Ascension Island in RAF L1011 - fab!)
Cheers
EGTB
