I'm a British B737 FO with a major European carrier. I can honestly say none of the European Captains have heard of Oxford or Cabair. They themselves don't give a damn where you trained so long as you've got hours on type.
My advice to wannabees. Go to S. Africa / USA and get your licence the cheapest possible way, buy a type rating and some hours on type. Its not how I did it. But in todays market there are thousands of CV's on every chief pilots table and all he wants to know is are you type rated with some line experience!!
I never trained in the UK but I was a QFI at Oxford Aviation Training School for a few months. I have never seen such a robbing organisation!!
