It's interesting that the takeover of LGW by GIP resulted in quite a speedy improvement in the passenger experience. By way of contrast, the takeover of STN by MAG has gone in the opposite direction. I know that there's a huge amount of redevelopment happening but EMA is also a very unpleasant airport these days so I don't hold out much hope.
STN was designed to be a much pleasanter airport experience but it just feels kind of trashed now. It's my local airport and LGW is much less convenient, but I now actively consider LGW much more than I used to. And it's true that Southend is a lovely experience, but it's catchment area is, in reality, very small and the range of routes is unlikely to improve. I'm sad they're cutting SXF.
