How long does it take to assemble an Airbus A380?
Airplanes are not built like cars where after completion, they are showcased at dealership to attract prospective buyers. For larger commercial airplanes, airlines place an order first and then wait for the airplanes to be manufactured, custom modifications completed, inspected by the airline and then delivered. It is a bit complicated process.

However, one of the A380s Emirates ordered, was manufactured and delivered in 80 days:


  Emirates are celebrating having their fiftieth Airbus A380 in service
  with the release of footage showing how 800 workers across Europe came
  together to build the biggest passenger jet in the sky in just 80
  days.
