somewhere else on the pages (in the Buzz) was a website very similar to this one only for airline employees. They had a TW section where they talked about this very topic-apparently New Orleans kind of recruited TW to serve the route, but the consensus was that it was a very shrewd flanking move that none of the other airlines could bother with, and would allow expansion into other countries/areas in Mexico/Central America easily (neither DL, AA nor CO would pull flights from their respective hubs to combat with TW), plus it would be something that would be non-competitive with Southwest.
