Super giant planes are, in my opinion, a terrible idea for passengers. Loading and unloading will take an hour, you will be crammed into the middle of five person rows, service will be awful, and they would reduce the number of flights, resulting in less comfort and fewer options.

I'm glad it's failing.

Apparently the biggest problem for double-deck passenger aircraft is the need for customized jetway bridges to access the plane.

It takes 45 minutes to load an A380 using two jetway bridges to its lower deck; adding a third bridge to the upper deck reduces that time to a little over a half hour.

Not to mention getting your luggage after and the hoards descending on customs on international flights...

Actually the worst part is when 800 people are suddenly cut-loose at a not-so-large airport to be processed by immigration officers (they still exist, at least in countries other than the United states). People can wait hours for that process to conclude.
