Sometimes if you want to fly somewhere without having to change or without having to pay inflated fares, then you have no option but to fly from a particular airport. I have to agree though, that there are areas of Prestwick Airport that do need to be upgraded - the train station and bridge, a larger departure lounge (sometimes it gets very overcrowded in there with nowhere near enough seats), new decor (there is too much purple at present, it's hoaching) a new airport slogan, and more cleaners.
