7. Southwest Airlines
When it began, we were both underdogs. Upstart swagger-filled Texans spitting in the eye of the establishment. But our companies worked together. And grew together. We made a habit of breaking the rules and a hobby of shattering expectations. We filled the airwaves with unforgettable ad campaigns like “Wanna Get Away?” and “Must Be Football Season.” We filled the skies with planes painted like whales and state flags. And we filled those planes with butts in every seat, year after year, till today Southwest has grown into the largest domestic carrier in America.
