It was 50 years ago, June 18, 1971, that Southwest Airlines made its first flight. Departing Dallas Love Field (DAL) in a Boeing 737-200 bound for Houston Intercontinental (IAH), the passengers on board would have had little sense of how much the dinky little startup they were flying would change the airline industry.

Yet now, 50 years later, as Southwest and other airlines recover from the worst crisis in the history of commercial aviation, the impact of the once-upstart carrier is reflected every time we take to the air in the United States, regardless of the airline we're flying that day.

Southwest made its first flight after years of litigation from entrenched Texas carriers Braniff and Trans-Texas Airways, which tried countless legal maneuvers to stop the new airline from taking off, rightly worried of the threat that Southwest presented.

That's because it was still the era of airline regulation, in which the federal government treated domestic air travel as a public utility and dictated what routes an airline was allowed to fly, and what prices it could charge. That meant that the primary way airlines could compete was by trying to outdo each other on product.

Southwest's founders, however — pilot and businessman Rollin King and Herb Kelleher, his lawyer — found a loophole, inspired by two small airlines in California. By operating entirely within Texas — and not crossing state lines — Southwest could avoid submitting to the Civil Aeronautics Board, allowing it to undercut the competition. And with low fares, the airline could target potential customers who were driving 250 miles between Houston and Dallas, or Dallas and San Antonio. Why drive five hours when you could afford to fly for 45 minutes?

The early years of Southwest were like the Wild West, far from the family-friendly persona the airline wears today. A motif of "love" could be found everywhere from the airport headquarters' name — Dallas Love Field — to the names of the ticket machines — "love machines" to the snacks on board — "love bites."

Then there was the sex appeal, with outgoing, personable flight attendants dressed in hot pants and go-go boots, and double-entendres wherever one looked. And that's not to mention the free-flowing whiskey on board.
