Slightly off topic, but a check in Galileo shows that BE are going to operate SOU-IBZ as an overnighter from the end of June, with a 3.5hr t/a in IBZ!! (presumably due to SOU's opening hours).
All of the new routes from SOU (except JER,BGY) are down as 142 or 143, so they must be getting some "new" frames from somewhere, or closing other routes.
