When Ann Coulter gets going, it’s hard to get her to stop. Continuing a several days-long rant against Delta on Twitter, Coulter slammed the airline carrier again Sunday, while promoting one of their rivals.

“I had a GREAT flight on @JetBlue yesterday, where the customer comes first! @Delta's CEO should fly @JetBlue sometime and pick up some tips,” Coulter wrote.

READ:Ann Coulter Claims Delta Incident Was Politically Motivated, Posts Texts With Attendant On Twitter

Coulter, 55, is a right-wing commentator who often appears on television and radio and does speaking engagements. Her feud with Delta began last week when she was moved from her original pre-booked seat on a flight. After the incident, she took to Twitter to disparage the airline, its employees and even went as far as to poke fun at the stranger that Delta had given her seat to.

“.@Delta motto: "How can we make your flight more uncomfortable?” she wrote on Twitter. “spends all this $$$ on beautiful aircraft & then hire Nurse Ratchets as flight attendants & gate agents.”

Nurse Ratched was the tyrannical, rule-enforcing nurse that was the antagonist in the novel “One Flew Over the Cuckoo’s Nest.”

Delta agreed to return the $30 that it cost to upgrade to an emergency aisle seat with more legroom, but offered a chiding statement in response to Coulter’s behavior.

“@AnnCoulter Additionally, your insults about our other customers and employees are unacceptable and unnecessary,” said Delta in a statement on Twitter.

Coulter was not pleased with Delta’s response.

She went on to say that the time she took choosing that specific seat was worth $ 10,000 and compared the company to fascists.

“But I love @Delta declaring my tweets unacceptable. @Delta now dictating acceptable conduct off the plane. NOT fascist at all. #Resist,” she wrote on Twitter.

According to Forbes, Saturday, the original mishap was caused by a glitch in which Coulter tried to change from a window seat to an aisle seat a day before the flight, but ended up back in her original seat.
