To disagree slightly with arpansingla, in my opinion it does not matter who you do your training with as long as it's JAR approved. (a fact backed up by 99% of airline recruitment teams)
No matter where you train, you will build up a network of friends (and thus future contacts) as well as meeting current pilots who will allow you to make an impression by simply talking to them. If you make an impression you will be remembered.
If you are an Oxford student, but a complete ****, it won't help you get a job. If you do the ATPL modular over 5+ years, work hard at networking (the most underated part of flight training, in my view) and are the kind of person others could survive with in a multi-crew environment- congratulations, you're a future airline pilot.
Don't spend unnecessary cash if you don't need to. £60,000 is a lot of cash and while Oxford is without doubt an absolutely fantastic school, there are others out there that you can go to and NOT have to sell your house...
Anyway, have fun researching...
Simon.
