Maybe now the price has been lowered it will attract more interest and a sale.
I think the "price" being lowered is more an issue of writing down the book value as an accounting trick - If anyone had come along with even a semi-decent offer thus far I think Infratil would've bitten their hand off, whether it matched the price or not.
Even if the airport's sold for £1 I think there's a legitimate question as to how the new owner will make money. FR quite obviously are unprepared to pay their way and successive managements over the last 10-15 years have failed to persuade any other significant operator to come in. I agree that the airport closing totally is very unlikely due to its strategic value, but people have to face the possibility that, if pax ops are the main source of losses, closing the terminal may be a way that Infratil/future owners will attempt to stem the losses. Either that or MOL pays more and we all know that's unlikely.
