1. LGA and DCA are slot restricted so SWA can't add capacity like UAL did for SFO-EWR. So its product vs product and price vs price. Two different target clientele for two different airlines.
2. SWA doesn't do ORD so non competitive route.
3. LAX and SFO that will be the routes I will be concerned about and watch.
4. If VX gets the gates I think it works in the favor of both SWA and VX.
