As per the title BA is to refurb 18 747 and at the same time increase CW capacity to 86 seats (plus the existing 14 F ). These aircraft will be used on the east coast routes and ignoring the argument of whether you personally like CW or crowed cabins I wonder if VS is missing a trick here by firstly loosing the capacity of 747 from LHR and secondly will BA being able to flood the market (extra 100,000 seats per annum) with the high capacity aircraft hurting the VS model of less seats available therefore in theory less lower priced bucket seats.
Well the demand's clearly there - VS have recently added a 5th daily JFK after all, and you rarely hear reports of empty J cabins on the JFK route on either airline so I suspect BA will fill the seats with new business rather than extract business from VS.
I guess the danger is if there's another financial crash or 9/11 that decimates business travel, BA are stuck with a fleet of ageing four engined planes with a lot more J seats they can't fill. Unlikely though, and the route network's big enough to match 'Super-J' with demand as required.
