ATLANTA _ Conservative political pundit Ann Coulter unleashed a tweetstorm on Delta Air Lines on Saturday night, complaining about being moved out of a particular seat with extra legroom that she had pre-booked.
In one tweet, Coulter referred to Delta as "the worst airline in America."
Coulter had booked a preferred seat in the exit row with extra legroom and was moved to a different seat in the same exit row, according to Delta. The airline said it "inadvertently" moved Coulter from an aisle seat to a window seat in the exit row on the other side of the aisle "when working to accommodate several passengers with seating requests."
Although Atlanta-based Delta has a mostly non-union workforce with pilots being the only major unionized employee group, Coulter asked: "Does your union hate you, @Delta?"
Delta responded via Twitter, at first apologizing and then attacking Coulter's actions.
The airline said it was sorry she "did not receive the seat she reserved and paid for" and would refund the $30 extra Coulter paid for the preferred seat.
Coulter at one point posted a photo of the passenger she said was given her seat.
In describing the series of tweets from Coulter, Delta said "what started out as complaints eventually turned into a public attack on the airline's employees and customers."
Delta continued with a statement Sunday saying, "We are disappointed that the customer has chosen to publicly attack our employees and other customers by posting derogatory and slanderous comments and photos in social media. Her actions are unnecessary and unacceptable."
"Delta expects mutual civility throughout the entire travel experience," Delta said in its statement.
The skirmish continued Monday.
