Long security lines? Strip-search pat down? Rude gate agent? As modern-day flyers, we’re familiar and now accustomed to the insta-service and insta-reaction of social media. And while, we’re assuming, millions of posts a day occur about lousy service at an airport, one tweet from a Minnesota family caught the eye of someone at Southwest Airlines, enough so that the entire family was asked to deboard. The father, Duff Watson, tweeted that his gate agent was extremely rude: “Wow, rudest agent in Denver. Kimberly S, gate C39, not happy @SWA,” he told CBS he said in the tweet. But then, the airline demanded that the family leave the plane, and said that they must delete the tweet in order to get back on the plane, Southwest confirmed. Kimberly felt threatened because of the tweet, according to reports. The family was ultimately allowed to reboard, and the airline has since apologized via email and offered a $50 voucher for all three family members, but Watson has vowed never to fly Southwest again.
