As a pax, even down the back, I will pay extra for the ability to arrive and exit the aircraft without half the world being with me.
This is quite a silly statement.
In a 777 you would have more people in front of you to disembark, if you were seated up the back.
An A380 is basically two A330s flying in formation. When they board and disembark, they process the two decks via two different air bridges. So in fact, you are quite wrong. Think about it!
Where it will get you however, is being processed through our very efficient customs and border protection facilities
