Cargo - would'nt put it past them but the ten gallon hat on a two pint management head DFW thing is will continue to perpetuate its own streses for Q with or without AIPA - not least being the odd tonne or two of pax bags left on the ground for AA to shuttle to LAX and then have them hauled across the PAcific by a 747 or 380. It was and will be a spec run at best.
B772 is correct - besides the 380 itself sometimes struggles with a fuel load of 230 tonnes to make the hop - esp this time of year. There are some lessons in physics 101 that need to be learned and the education is already expensive!
