Leo Hairy-Camel said "B777-200LR perhaps, LHR-SYD non-stop" and missed the point.
There are plenty of business seats available from the big operators on that run already...but at a price most of us can't afford.
What we need is a really good premium service on long haul flights that we can afford. Following the Easyjet short haul model, this usually means operating from smaller airports with smaller aircraft that enable the costs to be cut.
Despite the three business airline failures this year I am still hoping that decent seats at decent prices will still be possible in the future.
