I think Gin Slinger and WWW have hit the nail on the head, and you would not go far wrong heeding their advice.
A CPL/IR issued by the CAA/JAA, will only be issued when ALL required criteria has been satisfied.
Therefore a CPL/IR gained at Multiflight (random school), is EXACTLY the same as a CPL/IR gained at OATS or CCAT!
A little obvious I'm sure, but try not to attach any 'sweetners' to schools that other NOTHING different to any other fully approved school.
Geography and personal circumstances should be the ultimate deciding factor IMHO.
I think somebody already mentioned it but please...... 'smile if you have an Oxford Education'????????????
What utter marketing horse*****, it makes me smile everytime I see those sorry adverts!!
