Given Heathrows cost base, just how does anyone intend to make a J31 into Heathrow profitable?
With the exception of Liverpool, does any city with any sort of catchment have the passenger mix to make Heathrow profitable? IOM, JER perhaps.
Shetlands, Dundee, Carlisle, Derry.... not a (profitable) hope. The days of Sheds flying from Heathrow to Birmingham aren't coming back.
