A more remarkable statement he made is that he rather replace the B747 fleet with American planes, then with the A380.
I would really hope that the Boeing 747-Adv project will go ahead, after Cathay Pacific (who have expressed interest if* Boeing decides to go ahead with the project), British Airways is also expressing interest in the Boeing 747-Adv.
After all, the Boeing 747-Adv will have significant lower operating costs then the existing B747-400's, and not to forget, it also could be a very good competitor to the A380/A346/B773 (when looking at seat per mile cost). Secondly, it would fill in the gap that exists between the A346/B773, and the A380. Also the aircraft could be very wanted as a B747-Adv Freighter, with lower operating costs and the nose loading cargo door.
It will probably also be cheaper to acquire, since the development costs will be very low. That said, Boeing will need to sell not that many planes to reach break-even point, whereareas the A380 has high development costs and need a lot more sold to be profitable (although the aircraft do not compete directly).
What can't be forgotten is that the Adv will weigh 175,000 lbs less than the A380 but carry only 25,000 lbs less payload. The B747-Adv also requires less airport modification than the A380, meaning greater flexibility in network planning.
*A lot of "if's" around here, it seems that customers themselves are unsure if Boeing is going ahead with the project. It is now or never for Boeing, if they wait to long customers could be scared away/lost (they will be looking for other alternatives), and it would be too expensive to keep the current Boeing 747-line open.
What could possible other (future) customers be? KL, CX, AI, JL, ANA or Cargolux? Maybe even LH and Qantas? I can't see those airlines replacing all of their B744 fleet with A380's, that would be too many seats to fill. And since there is such a gap between the A346/B773 and the A380, we maybe could also see some orders from them?
Time will tell what happens, but if I'm a dreamer, I would wish that Boeing announces the go ahead for the B747-Adv project at Le Bourget, and maybe even the first orders for it! Sigh......
