The story goes that Duff Watson was waiting to board a flight from Denver to Minneapolis when he posted an angry tweet about one of Southwest Airlines’ agents following a disagreement.

Mr Watson was an “A-List” passenger, which means he gets priority boarding. But a gate agent wouldn’t let his 6-year-old and 9-year-old board with him.

As he left, perplexed about the situation, he moaned about his treatment and said he would be “sure to tweet about it”.

That he did.

And to his surprise, soon after taking their seats the family of three was asked to leave, US television station WWCO reported.

“I was left, you know, very upset, very embarrassed, very humiliated,” he said.

According to Watson the tweet, which he was forced to deleted by the airline, said something like, “‘Wow, rudest agent in Denver. Kimberly S, gate C39, not happy @SWA’.” 

Southwest Airlines said the incident was under review.
