Sorry boys I was there in 2002/3 when British European did it in the Dash 8 200 series. 37 seats max but loads were always under 50% and usually 30-40% in winter.
Thats why it was past to Eastern before winter 2003 as their J41 was only 29 seats. Started OK then Easterns fares slowly killed it. Who d pay £300 return IOM NCL for lesure and pleasure
