As you say WB,
If people like the 777 more than the cattle truck (A380) then they will fill the seats
From 1st hand experience the 'cattle truck' passengers on deplaning, almost without exception, commented that the machine was brilliant and
'SO QUIET'.
As it always has been, the punters will choose to fly on the convenient, cheapest option available. Whoever offers that, will fill the seats.
Good luck to one and all, but the cattle truck will be hard to beat.
