From The Boyd Group's great website, with apologies:

Regarding the A380:

"From Airport Magazine, January/February Issue: "ThyssenKrupp contends a conservative stand layout with two bridges (note: a 747-type gate arrangement) ... will take 45 minutes..." to deplane passengers.

That oughta set real well with the poor clown sitting back there in seat 89F. The A-380 pulls into the gate, and the minutes elapsed between when it stops and when he finally reaches the door of the airplane is roughly the equivalent of the flight time between LGA and Boston. That's nearly 200 miles. But this guy's only going several dozen yards. Great for enhancing hubsite connectivity. Airline planners will be thrilled to pad in an additional 45 minutes of minimum connect time specifically for passengers going to or from an A-380 flight. Great hub efficiency.

But not to worry, WhaleJet fans. ThyssenKrupp goes on to note that the A-380 can be deplaned or enplaned in as little as 24 minutes. All it would take is the installation of just four - count them - four, boarding bridges, including "...a cantilever, over-the-wing bridge (COB) connecting to the lower rear door, (plus) a forward lower deck connection, (plus) another forward bridge connecting to the upper deck..."

Sounds sorta like instructions for do-it-yourself heart bypass surgery."

How many US airlines and airports have the cash to invest just to service this turkey? As a pax, I would avoid an A380 at all costs!
