I haven't checked their prices lately. What I do have to say about Southwest is that I am sorry that I didn't book with them this year. We usually fly southwest, but we went with US airways because they had such a good deal, but now the extra expenses are adding up. Southwest gives lets you bring your first 2 bags for FREE, plus they give you LOTS of snacks and drinks for free. Also, they are really great if you need to move your dates, change routes, etc. without ever charging fees. Plus, they fly you directly from where I am at without layovers.
We ended up with a layover, $150 per flight charge for any changes to the flight (more than we paid in the first place!), $15 fee for FIRST bag checked, NO in flight snacks....grumble. Next time, I'm flying southwest again.
