You don't know what you are talking about.
The A380 was built for international flights, not jump flights from Minneapolis to Seattle.

The largest problem with most international airports is not finding a ladder that is high enough to get to the door, but the number of flight paths available.

The A380 hold 35% MORE passengers than the 747, there by reducing traffic between international airports by 30%.

The basic aircraft is the 555 seat A380-800 (launch customer Emirates) maximum seating 848. The 590 ton MTOW 10,410km (5620nm) A380-800F freighter will be able to carry a 150 tonne payload and is due to enter service in 2008 (launch customer FedEx). Potential future models will include the shortened, 480 seat A380-700, and the stretched, 656 seat, A380-900.

On July 24, 2000, Emirates became the first customer making a firm order commitment, followed by Air France, International Lease Finance Corporation (ILFC), Singapore Airlines, Qantas and Virgin Atlantic. Together these companies completed the 50 orders needed to launch the programme.
Later, the following companies also ordered the A380: FedEx (the launch customer for the A380-800F freighter), Qatar Airways, Lufthansa, Korean Air, Malaysia Airlines, Etihad Airways, Thai Airways and UPS.

So far 150 aircraft have been ordered.

Looks like a lot of airlines don’t agree with you that it is TOO big. It has its purpose.

By the way, I don’t know where you got 700 for the break even point. According to this article on the BBC, it is 250.

“Noel Forgeard said he expected sales of the A380 to comfortably exceed 250, the number required for the huge aerospace project to break even.”
