Savannah Chrisley was denied boarding on a Southwest Airlines flight after insulting an airline employee during a heated confrontation.

The Growing Up Chrisley alum, who was headed from New York to Tennessee, described her ordeal in videos shared on her Instagram Stories April 20. "So I went to board my flight, to get on, and he told me that he had to check my bag," she said about the employee. "I was like, 'OK. If you wouldn't mind, I'm gonna take my bag on the flight, see if I can't make it fit and if not, I'll check it.' His exact words were, 'No. That's not happening.'"

Savannah, 25, continued, "I was like, 'OK? Um, let's go ahead and put a tag on it in case I have to check it because I would love to see if there's any room for it.' And he goes, 'You're being an unruly passenger.'"

According to the reality star, the plane's pilot then got involved. She said he "told the Southwest attendant that he needs to calm down and that he was going to find a place for my bag," and that the employee looked at him and told him to "stay out of it" and then told her, "Ma'am, you're not flying on this flight."

Savannah added, "When this Southwest attendant told the pilot to calm down, I told him that there was no need for him to be an a--hole today, and then he threw me off the flight...I also stated that had a 10-year-old that I had to absolutely get home to tonight and well, the Southwest attendant said, 'I don't care.'"

The reality star gained custody of her brother Grayson, 16, and niece Chloe, 10, after their parents, Todd Chrisley and Julie Chrisley, were sentenced to 12 and seven years in prison, respectively, for tax fraud and other charges last November.

Savannah continued, "After he told me he didn't care if I got home to my 10-year-old, I told him that I hope he found a 'better purpose for his life.' Maybe I shouldn't have said it. But the devil came over me, and the Jesus did not come out."

A rep for Southwest told E! News in a statement, "We're aware of the video and our initial reports indicate a different story than the one from the Customer's account."

The rep continued, "She arrived at the gate late in the boarding process and was asked to gate-check her bag due to the overhead bins being full and to avoid delaying the more than 100 passengers already onboard the aircraft. She loudly and repeatedly insulted several Employees and as a result, the Customer was denied boarding on her original flight, and traveled on a later flight the same day."

Savannah said on her Instagram Stories that she was rebooked on another flight, which had an additional stop in Baltimore, unlike her original one, which flew direct. "But hey," she said, "Southwest 1, Savannah 0."

She added, "Southwest you suck, but your pilot was kind of hot."
