9 is the maximum amount of flights that they will operate, however I am confident they will sell all the seats available with only window seats and the adjacent aisle seats being on sale, so A,B and J,K will be on sale, which is about 140 seats per flight. IIRC window seats are £150 and aisle £100.
I was astonished at the number of flights Biman suggested they might operate until I read (above) that they're only selling 140 seats per flight.
But still, that means there's + / - 1200 seats potentially on offer, which seams a heck of a lot. How many enthusiasts are there in UK (and I suppose further afield on the continent) and of that total, how many will be able to afford the price of the fares, plus getting to and from BHX?
That said, great news that this project still still on track. Should provide some positive national, and potentially worldwide, good publicity for BHX, and indeed, Birmingham.
