Manchester Flights April/May 2011

Just looking now at prices and so on.
I know the MAN - MCO route is going A330 wef April 2011 but I thought that the later service (VS73 and VS 74 return - 747) was continuing as present patterns (selected week days). But, when I look at flights for the above period, VS73/VS74 seems to appear and disappear (for the same day!).
I am thinking of going out PE on an A330 and coming back on the later 747 flight - PE - up in the bubble.
Anybody shed any light? Or am I being too keen on looking right up against the 11 months cutoff?
