As of the time of this posting the cost of an economy class round trip flight on this QANTAS A380 from Los Angeles, California to Sydney Australia is $1,497 USD. I recently had the opportunity to tour this aircraft and while it was huge, the economy seats were small and leg room tight for someone as tall as I am. I know this for a fact because I tried one on for size.
The aircraft itself was amazing. I was stunned by the incredibly high-tech cockpit and at its massive size.
The A380 has an range of 9,756 miles which would guarantee that I would run out of ass before it ran out of gas.
