Jason Ivey has indeed vacated the post of Operations Director, although the official word is apparently that it was his decision to leave. Jon Horne has been moved sideways from his post of Interim Managing Director to become Chief Operating Officer so I assume he has effectively become Operations Director in Jason's place. I think Jon has the experience to satisfy the CAA for the role of accountable manager in that position.

That's an interesting suggestion but would involve departures at around 0630, 1000 & 1700 from DUB to SEN with flights ex SEN at 0800, 1445 & 1930 to DUB. Alternatively you could have just the 0630 & 1700 from DUB and 1445 & 1930 to DUB and use the aircraft on both, say, SEN-RNS & SEN-GRQ. An interesting discussion point but probably nothing more than that in reality I suspect.
