WW
From what I can see of the schedule so far there is scope for an extra flight on days 1,2,3,4 and 7 and for two extra flights on day 6.
The rotations don't lend themselves to an A321 turnaround time so I expect it to be 5 B733 aircraft, which would match to BHX losing an aircraft for Summer 09 over Summer 08. I'd be surprised if there was a 6th unit to be based in MAN for next year, but if it was I expect it to be the A321 coming back which may open the possibility for longer sectors... Canaries perhaps? The A321 has been fantastic this Summer in terms of loads and onboard sales so WW would be mad not to have it again next year!
