I don't really understand, why the A380 should be compared in any way to the XXX Boeing.
These aircrafts have completely different markets, different technical specifications,
different usage.

The interesting question is :
"Who is going to make more money, and lead the market, in 10-15 years ?"
- Airbus with a big plane on top of the series
- Boeing with a faster plane.

There is a market for both planes. But the problem is not to build a good plane, the problem is to find (enough) carriers to buy it.

Actually, Airbus has a project and clients, Boeing has a new project and still no client for it.

Boeing did lead the market in the 70s and 80s, now Airbus sells more planes.

Dear American friends, you must accept this new reality
