Great budget airline.

Southwest airlines is kind of a budget airline. They usually have some pretty cheap flights, especially if you can catch a good special. Their flights are usually one way, but sometimes they have a sale where a lot of flights are $39 if you book in advance. This is the main thing I like about southwest is that they are usually cheap. Of course, if you don't book in advance, it's still just as pricey as other airlines. The downfall of Southwest is that they don't fly everywhere. There have been many times when I was looking for a flight only to find that Southwest doesn't fly there. They are cheap but limited. Their customer service and staff are usually pretty nice too. Overall its a pretty good airline for the money. If American has a sale to the same destination, I usually tend to go with them because I think they are a lot friendlier and I like their planes more!
