We turn now to how an angry dad's tweet got his family kicked off their plane. Duff Watson was upset by the way his kids were treated when they boarded the swaes flight and showed it and paid the price and Ryan Owens has the story. Could I maybe get that headset please? Reporter: Complaining to the airlines got Adam Sandler tased in "Anger management." Do not raise your voice. I wasn't raising my voice. Calm down. I'm calm! Oh! Reporter: These days passengers are more likely to spew their frustration on social media. But watch what you tweet. Just ask duff Watson. Very upset. Very embarrassed. Reporter: On Sunday Watson and his 6 and 9-year-olds were traveling home to Minneapolis on southwest airlines from Denver. Dad trafs a lot so he is an a-list passenger. They get to board first. His kids may be adorable but they aren't a-list so when they tried to board with him he said the gate agent wouldn't have it. I said real nice way to treat an a-list and I'll be sure to tweet about it. Something to the effect of, wow, rudest agent in Denver. Not happy. Reporter: As soon as they settled into their seats they were asked to get off the plane. He says the agent felt the tweet was a threat. She said I'm going to call the cops. I thought something bad was going to happen like my dad being in jail. Reporter: Nobody was arrested but Watson says the agent would not let the family reboard until he deleted the tweet. He did. There were no threats made. Reporter: Dallas based southwest sent a statement acknowledging a conversation about the airline's family boarding procedures escalated. But Watson says southwest lost a loyal customer. This dad may be a-list but he says southwest is now on his no-fly list. For "Good morning America," Ryan Owens, ABC news, Dallas.
