I currently study at Egnatia Aviation on the Integrated Program, just starting IR now, and would highly recommend the school. The school is very reasonable with its pricing and as a bonus provide accommodation and transportation to and from the school which is great. The aircraft are quite new and well maintained, on average there is good availability to fly and the instructors are always willing to help. From what others have told me and what I can see it is the best flight school in Greece.
