An American Airlines passenger was duct-taped to her seat as she allegedly attacked a flight attendant and erupted into a profanity-fueled tirade, bizarrely admitting to trying to poison her father.

Ketty J. Dilone is accused of walking and yelling throughout the cabin of the Las Vegas-bound flight, where she verbally threatened multiple flight attendants on Sept. 16, according to the United States Attorney’s Office for the District of Nevada.

Dilone was taking off on a connecting flight in Charlotte, NC, during a return trip from the Dominican Republic when chaos unfolded in front of her fellow passengers.

Flight staff were forced to restrain Dilon with zip ties and duct tape due to her in-flight behavior, authorities said.

Ketty J. Dilone was arrested last week after allegedly assaulting an American Airlines flight attendant.

After being restrained in her seat, Dilone allegedly kicked a flight attendant and caused the worker to fall.

A viral video posted to TikTok captured her foul-mouthed outburst, where she can be heard shouting that the restraints are hurting her.

“You don’t know what the f–k I’ve been through, bitch!” Dilone screamed toward a flight attendant. “Kill yourself, bitch! You wanna die, bitch?”

Dilone then bizarrely admitted to putting “roach poison” in her father’s coffee when she was 11 with the intention to kill him.

“It didn’t work,” she calmly said. “And in DR (Dominican Republic), we call it ‘Tres Pasito.’”

Tres Pasitos — which means “three little steps” — is a potent pesticide used to kill cockroaches and mice that is illegal in the US, according to the US Environmental Protection Agency.

Dilone appeared to settle down momentarily as she started singing the chorus to a song in Spanish with the same name.

However, seconds later, she again began flying off the handle.

A viral video posted to TikTok captured her foul-mouthed outburst, where she can be heard shouting that the restraints are hurting her.

Dilone then bizarrely admitted to putting “roach poison” in her father’s coffee when she was 11 with the intention to kill him.

“So if anybody wants to kill somebody, put roach poison! But make sure it’s not expired, and make sure you put a lot of it!” she shouts, alleging that when she tried it on her father, it only “put him to sleep.”

After a brief moment of silence — with tension still building in the cabin among worried passengers trying to ignore her outburst — Dilone starts screaming that “the show’s f–king over” and rambling on with nonsense before the video ends.

The FBI arrested Dilone after the flight touched down at Las Vegas Harry Reid International Airport and she was transported to the Henderson Detention Center.

She was charged with one count of interference with a flight crew and one count of assault by striking, beating, or wounding.

Dilone made her first court appearance on the charges in Las Vegas on Sept. 18.

A preliminary hearing is set to take place on Oct. 1.

If found guilty, she faces a maximum sentence of 20 years in prison.
