After reading an article about flybe and the IOM, it seems MAN gets an increase.
Flights seem to be 32 weekly each way, compared to the current 23 each way.
Mon to Fri sees 5 daily with 2 on Sat and 3 on Sun.
This is compared to 12 weekly (2 daily most days) at BHX and 24 weekly (3 daily most days) at LPL. (LPL now sees highest frequency in the UK for the IOM due to easyjet also on the route)
