Stansted is very dead compared to what it used to be. I've noticed in the last couple of years it's much quieter, a few weeks ago I was on a flight in early evening and there was hardly anyone there and pretty little flights. Really does need new owners to re-invigorate it as it's a shadow of it's former self. I used to travel through there quite often in 2006 or so and the difference is amazing, it seems to have declined dramatically in the last 12-18 months especially.
Hope you noticed too the Car Park Ryanair have turned Stansted into this Winter, they have hugely reduced their STN schedule as they grounded 80 aircraft since last October, the airport picks up and is seriously busy come late March.
