There is a reason that they arent answering emails about their Fulltime JAA groundschool, it turns out from the UK CAA that they are definitely only approved for DL courses out of Sanford. The 30 Sept schools listings on the CAA website also confirms this.
This seems like a wannabe con maybe, i.e. lets advertise a course we dont have approval for and see how many we can sucker in maybe??
Also other alarm bells ring when you read the page it goes towards, "Be one of the 1st 20 to enroll " and then on the next page read about their capacity "JAA ATPL classrooms, each capable of holding 16-20 students." So the first 20 are the only 20....(yes they could have 2 or more classes of this unapproved course, but that means a lot discontent if 20 paid less $ than the other 20).... maybe time for a Delta rep to explain this to the wannabes of pprune??
