MINNEAPOLIS (AP) - A Minneapolis man and his two children were asked to leave a Southwest Airlines flight in Denver after he tweeted about a boarding disagreement.

Duff Watson says that as an "A-List" customer he has priority boarding. But a gate agent didn't allow his two children, ages 6 and 9, to board with him Sunday on a flight to Minneapolis.

Reports Watson says he tweeted that the gate agent was rude and that soon after they got to their seats they were asked to leave the plane. He says the agent felt threatened because of what he had tweeted. Watson says they could not return to the flight until he deleted his tweet.

The family was eventually allowed to board the flight. Southwest apologized to Watson in an email and gave him $150 in vouchers.
