Two sisters rushing to see their dying dad were booted from an airplane after getting into a squabble with the flight crew — causing them to miss the final moments with their terminally ill father, according to a report.

Debbie Hartman and Trisha Baker were about to take off on an Allegiant Air flight from Orlando, Florida, to Asheville, North Carolina, on Monday when the ill-timed brouhaha erupted, WKMG-TV reported.

Before the plane took off, Baker, who was seated apart from Hartman, received a troubling text message that their dad in hospice care had just hours to live.

“I didn’t know if my sister was getting the same text so I thought I need to go back there and console her,”’ Baker told the CBS affiliate.

When Baker got to her sister, a flight attendant ordered her to sit down.

“She said, ‘You need to sit down,’ and I said, ‘Well, can I just sit here? I just want to console my sister. We just got word that my dad’s dying,’ ” Baker said.

Hartman admitted she began freaking out and the situation only got worse.

“She (Baker) said, ‘You’re being very rude. My father is dying and I’m comforting her’ — and they said she needed to keep her personal problems off the plane,” Hartman said.

The flight attendant called the captain, who then turned the plane around and went back to the gate, where security took the sister off.

“They told us we were a threat to the flight and I just couldn’t believe it,” Hartman said. “People were like, ‘What’s going on?’ ”

A woman who claims she was a passenger on this Allegiant flight and witnessed the confrontation blamed the flight attendant, according to WKMG.

“The most inhumane, deplorable thing I’ve ever seen any human being do,” the woman said on YouTube.

The sisters said their dad died a short time after the on-board confrontation.

Allegiant said they’re looking into the incident.

“At Allegiant we rely on our crew members to provide and oversee a safe environment for every passenger, on every flight,” according to an airline statement.

“We expect that authority to be exercised both judiciously and consistently, with empathy and with good judgment. We take this customer feedback seriously and are in the process of conducting an investigation into what occurred.”

Hartman said heads need to roll at the airline.

“I would like to see them in some way be punished in a way where people understand. This is not humane — 100,000 percent I blame them. They were the gate between keeping me from my father to say goodbye,” Hartman said.

“I don’t think they should keep their jobs, to be honest with you. They don’t have heart. They didn’t care that I wasn’t going to [get to] see my dad.”
