Why US Carriers NEVER ordered the Airbus A380

The Airbus A380 saw great success worldwide, becoming the defacto aircraft of choice for Emirates and a flagship plane of Qantas, British Airways, Air France, and many more to name a few. But it never got the same success in the United States or the western hemisphere. Why did none of the big three, United, American, and Delta, order the Airbus A380? What would it have looked like had they ordered it, Airbus’ biggest plane, the A380, was certainly within reach of US carriers and should have ticked all the boxes for an airline to turn a considerable profit.
