MerchantVenturer, as far as I know the BRS-NCL route is doing very well. But even that is no indication on whether British Airways will stop flying the route.
British Airways within the last three or four years (at different times) has served Newcastle to Aberdeen; Belfast; Birmingham; Cardiff; Copenhagen; Cork; Dublin; Edinburgh; Isle of Man; Oslo; Paris CDG and Southampton. Of these, only CWL and EDI were plugged due to bad loads, the other 10 routes apparently had good loads, so much so frequency was increased on ABZ, BHX, DUB and SOU.
So why have BA ditched ALL of these routes, considering Braathens managed to fill a 737-500, as opposed to BA's Emb145; Air France operate three or four Bae146-2/300 flights daily, soon to be joined by easyJet; Cimber Air managed three flights daily to CPH in contrast to BA's one; and Ryanair had to increase to double-daily to keep up with demand after one month.
In response to starone, if it was down to the subsidary carriers, who owned all shares in Brymon Airways and Cityflyer Express? British Airways.
So you see, BA are earning a well-deserved reputation for kicking the regions of the UK, so I wouldn't regard any well-performing routes as safe where the 'World's favourite airline' are concerned.
I think BA as the national flag-carrier has a responsibility to make sure that it's own country is well connected, and connect the regions to Europe were suitable. It is rediculous to travel down from somewhere like Newcastle to London to fly to Oslo, when there is quite sufficient demand for a service direct...
