Thanks chaps. I didn't realise any of that.
A thought, though...........does it indicate perhaps that these places have a little way to go along the CRM path to the 21st century; nothing (well, almost nothing) used to irritate me more than being referred to, especially in the 'welcome' PA, as a 'co-pilot' or worse 'my co-pilot'. The position is F/O or SFO.
Just an observation.
Cheers.
