Just a quick clarification (which does not really alter your overall point). The Wright Amendment was to drive traffic to the soon-to-be-built DFW which could not be viable while having a competing airport. The Amendment was an effort to enforce an early 60's agreement to move all traffic to DFW, but since Southwest was founded after the agreement the court upheld that it did not have to follow the agreement.
Enter the Wright Amendment to protect, not Southwest, but Braniff's, Ft Worth's and DFW's investment in moving to DFW. It allowed commercial passenger flights out of DAL only within TX or on planes holding <57 passengers to AR, LA, NM and OK. To get around this passengers could book a flight from DAL on Southwest to, say, OKC and then book a separate flight from OKC to another location served by Southwest.
Imagine...more moving parts means more chance of failure. Being on a plane where the wall does not deploy means no lav for that (and possibly the next) flight.
And God help the people sitting near that thing when someone leaves a package with extra smell...and then drops the wall. No longer worried about the silent farter in the seat next to me. Just don't want to be sitting within several rows of that thing.
