fleon's story matches my experience - I reapplied via OAA 13 months after my initial application and received a phone call inviting me to assessment. However, the next question was 'Have you ever applied to FR before' to which I replied I had. At that point the lady on the phone very apologetically said that the Ryanair policy is no reapplications.
CAE have also failed to progress my application on learning I have been rejected once before, despite it being over 2 years prior.
