Southwest Airlines TV Spot, 'Class Dismissed: $50'

A teacher watches through her webcam in horror as her students make a mess of their houses with homemade volcano science experiments. While she instructed them to add only a tiny amount of vinegar, the kids don't hold back and giggle as colorful bubbles and smoke erupt from their creations. Southwest Airlines says that, like this well-intentioned educator, sometimes you just need to get away from your day-to-day. The airline announces select one-way fares starting at $50.
