At-the-airport Upgrade Specials (prices from Shanghai)

An often asked question - "how much to upgrade at the airport?". So, while it *entirely* depends on the route and how busy the flight is, here's at lease one idea for one-way from Shanghai to China.
Rather interestingly, this was on the counter at the Upper Class check-in, so I guess it's aimed towards gold card holders who aren't travelling in J.
So...
Economy > Premium = £240
Premium > Upper = £960
Exit Row = £40 (no different to paying in advance, according to the website)
Extra Legroom Seat = £20 (no different to paying in advance, according to the website)
All one-way, of course. Not sure if you would earn on these "specials" either, but I would imagine so.
