It's tempting to fly Southwest Airlines these days to avoid being totally extorted by the bigger carriers, even if you have to endure seven layovers between New York and Chicago. But by now you've probably heard about the Southwest flight that had to make an emergency landing after the roof literally tore open last week. Scary, sure. But that's not necessarily cause to avoid flying Southwest altogether, right? Well, yesterday three more Southwest planes were found to have cracks similar to the five-footer from last week.

I guess we now know Southwest's secret to keeping their flights cheap.
