Delta hit back at conservative commentator Ann Coulter after her daylong tirade because she had her seat reassigned on a flight Saturday.

Coulter, who had been tweeting insults at the company and the woman who was seated in the preferred seat she had purchased throughout the day Sunday, will receive a $30 refund for the seat, Delta said in a tweet.

"@AnnCoulter We're sorry you did not receive the preferred seat you paid for and will refund your $30," Delta tweeted.

"@AnnCoulter Additionally, your insults about our other customers and employees are unacceptable and unnecessary."
