Isn't the first flight due at the end of this year?
Regarding the interior fit, I doubt we'll see the shops, gym etc. touted in some corners. However, the airlines have an opportunity here to offer more space in all classes. Not much of a difference to First or Business given current products available, but the addition of an inch or two to the economy seat, in width and pitch, offered at the same price would give the A380 operator a clear advantage. I believe the aircraft's performance would support this?
