Why do you think the W/A was born? And don't use the BS answer of, to protect DFW.
<sigh>
The Wright Amendment was created almost a decade before AA hubbed DFW (that was done in 1981 for the history challenged), and about five years before they moved their HDQ there.
So, if you're about to go down the rabbit hole of saying that Wright was written to protect AA, which someone eventually tries doing every time the topic comes up, it's pretty far from the truth.
The reality of what DFW had for service in 1971 and today are about as far apart as it can be.
So yes, the Wright Amendment really was about protecting the investment that both cities made in the greenfield development located some 20 miles from both downtown areas.
Fort Worth had no choice but to close Amon Carter/Greater Southwest Airport when DFW opened, because it was directly in the flight path. AA's current HDQ sits on the property which was redeveloped quickly into what we know today as Centerport.
Thus, there was no going back for Fort Worth, and that's when the lawsuits started.
It's been a lesson for almost every new airport construction project since then to close down the runways almost as soon as the new airport opens.
All that said, WN, AA, and BN before them all found ways to make the Wright Amendment work in their favor.
