Conservative author Ann Coulter fired a fury of tweets on Saturday evening condemning Delta Airlines after she claims she was forced to move from her pre-booked seat.

Coulter's tweet storm included criticizing the airline's protocol, WiFi, and even shaming another customer by posting a photo of the passenger taking the author's seat.

Delta Airlines called Coulter's posts "unnecessary and unacceptable" in a statement sent to the Washington Examiner.

"Each of our employees is charged with treating each other as well as our customers with dignity and respect. And we hold each other accountable when that does not happen," the statment reads. "Delta expects mutual civility throughout the entire travel experience."

Delta isn't the first airline to come under fire for removing a passenger from their seat this year. In April, United Airlines faced intense criticism after a video went viral of airport security forcefully removing a customer from his seat on a flight he paid to be on.
