Very sadly, I do sort of see Flyga's point. I have never flown from Prestwick and have only visisted it once so perhaps I'm not one to judge but it did seems a little shoddy and anybody who does buy it is going to need to invest a lot more in improving it for it to have some form on long-term and sustainable future. Alternatively, you may choose to not upgrade it and just make landing fees virtually nothing and hope that basically Ryanair, Wizzair and perhaps the odd charter see the value of it in that way and increase their presence there!
