Delta airlines and Ann Coulter are exchanging a few war of words on Twitter.

Over the weekend, Coulter, a conservative political pundit and author, tweeted out her misgivings with Delta, calling it “the worst airline in America.”

Coulter said she was moved from her seat for the sake of an “emergency.” When she asked about why they moved her, no one gave her a straight answer, she said.

Coulter also tweeted a photo of the passenger who took her seat.

Coulter didn’t stop her rant there. She tweeted out insults at the passenger and the Delta staff.

Delta issued a response to Coulter through social media, promising the political commentator a full refund.

Delta then issued an online statement, saying the company felt disappointed with Coulter’s insults.

"Her actions are unnecessary and unacceptable," the statement added. "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."

Delta said Coulter booked seat 15D, which is on the aisle, just 24 hours before the plane took off. The airline said it moved her to 15A, which is by a window, to help other customers who also had seating request, Mashable reported.

Delta also tweeted out to Coulter, apologizing in advance for the mixup.

Coulter had the last word on Sunday evening, continuing to tweet her misgivings with the airline.

Delta’s hiccup with Coulter comes at a time when airlines have faced tremendous scrutiny for how they’ve handled passengers. United Airlines made headlines earlier this year after men in security outfits dragged a passenger off a flight.

Similarly, a Utah couple said they were kicked off a flight after they sat in different seats than the ones they had purchased.

An online video also showed the aftermath of a tense moment between a flight attendant and a mother with a baby. The flight attendant allegedly violently took the baby stroller away from the mother, which infuriated a fellow passenger, the CNN reported.
