Thought I would bump this thread to see if anyone has had anymore recent successes.

Have been trying to get some Z seats released for a 241, got some dates booked already in June, but wanted to move it forward by a few days. F is wide open as the route is off peak, but its a Sunday I am after. Have tried subtly to ask if there is any way of putting in a request to open these seats, each time met with 'we aren't able to do that', once its gone its gone, although having monitored this from a year out it was never there! Hang up and try again the following day, same response. Maybe as I'm lowly silver?? Maybe not through to the right person? Problem is I commence my journey on Sunday with a long stopover in London, as of Sunday it will be no more changes possible for me.

Any other results out there?
