Has there ever been any science or reasoning behind flight numbers and how they are chosen?
My first guess would be they are based on longitude/latitude axes. I realize direction plays a role as far as odd/even flight numbers are concerned.
BA 001 was the East to West 'flagship' flight so to speak
AA 001 is the East to West 'flagship' service NY-LA
Is there any science or practicality in assigning flight numbers? Or is it random?
