Good valid points by Planespeaking,it's simple :lack of investment=decline in services and Pax.Years have gone by with very little development, continuing in this vane will only accelerate SOU demise.I can't see any forceable change,it's a missed opportunity to give the South a viable thriving airport ,an alternative to London ,after all there's not many airports that have a railway station and motorway network on there doorstep!
imagine what BOU would be like with these facilities !!!
