Oxford and Bristol
EGAC
Your doing what i did last year: Oxford groundschool and BFC flight training.
Both places very good.
If you don't already know people at BFC. Then Nasib Otaqui and Rowan are great IR instructors.
When doing the CPL, the re is a part time instructor called stuart mcmanus. He is excellent, but as said part time.
Everyone friendly and helpful, so enjoy!
