GLA had one single non stop GLA-Europe (CDG) that I can recall
True - I used to operate that rotation. Evening MAN-GLA with Manchester cabin crew. On the turnround MAN crew get off for a nightstop and replaced by GLA cabin crew for the late GLA - CDG. Arrive late into the Paris hotel in time for cups of tea and bible studies
Reverse the process in the morning picking up "our" crew in GLA for a mid morning GLA - MAN.
All lots of fun, 4 sectors in the log book and the rest of the day off..
Never more than 20 pax though ....
