I'm a DAL pilot and, due to location and family circumstances, have flown SWA (as a paying customer) frequently over the last two years. It is what it is...on time, comparatively inexpensive, good inflight service, and well-trained pilots. The MX thing is a bit troubling but SWA is a great airline. I know lots of guys flying for them and I can vouch for their professionalism and expertise. Wouldn't want to fly them coast to coast but don't have to.
