How Many Intra-Texas Routes Does Southwest Airlines Operate?

When it comes to domestic US air markets, there are few as fascinating to explore as that of Texas. For the most part, passengers will travel between states when flying, with relatively few examples of strong air travel markets that exist within a single state. In California, this kind of air travel market does exist, but pretty much with a single north-south market, with the majority of flights connecting Los Angeles and San Diego to the Greater San Francisco Bay Area and Sacramento.
