history shows that aircraft capacity is ALWAYS a winner - look at the growth is the 737, 707, 747, 767, 777 for example
The ability to move larger numbers of passengers with the same aircrew and number of airframes is always one airlines crave
As the 747 fades the A 380is the only game in town to put a lot of bums on seats - remember it can shift 700++ in current versions
God knows how many Ryanair could get on board.............
