An irate woman was booted from an Endeavor Air flight — for refusing to sit next to a Rochester mom and her bawling baby boy.

Beauty consultant Marissa Rundell was flying from JFK to Syracuse on Feb. 6 when she said she was insulted by the blonde, potty-mouthed woman.

“This lady thought she was going to be rude to me and Mason, now she had no way home today,” Rundell wrote on Facebook, along with a video that captured part of the incident.

Delta, which operates Endeavor Air, confirmed that the ill-mannered lady was kicked off.

The young mom, who was heading home after visiting her brother in Brooklyn, told The Post the ordeal began when the passenger started “freaking out” about having to sit in the back of the plane, saying it was “f–ing bulls–t.”

“I asked her not to use that language around my son,” recalled Rundell — whose child is 8 months old. “She told me to shut the f–k up and shove it.”

“Then she started complaining about my baby,” Rundell said.

Footage posted by Rundell starts with the woman gathering her bag and coat from an airplane seat and angrily proclaiming: “I’m not sitting next to a crying baby!”

“He’s not going to cry the whole time,” Rundell replies, with an exasperated sigh.

“I was appalled by the way this lady was acting,” the mom told The Post. “I’ve never experienced anything like this before.”

The woman can be seen on video asking for a flight attendant’s name and threatening to put her job in jeopardy, after being told she’ll have to be removed for insulting Rundell and her baby.

The footage ends with the woman apologizing and stating she was “really stressed out.”

Rundell told The Post the lady continued pleading and finally left the aircraft after 10 minutes of back-and-forth with the flight crew.

“I hope she realizes she was acting like a child and never treats anyone like she treated myself and the flight attendant again,” Rundell said.

Delta thanked the Endeavor Air flight attendant and apologized to other customers on the flight.

“We ask that customers embrace civility and respect one another when flying Delta,” said Delta spokesman Michael Thomas. “This customer’s behavior toward a fellow customer was not in keeping with those standards.”
