Michael Allen Haag, of Boulder, was arrested after allegedly groping female passengers aboard a Frontier flight and then urinating on the seatback in front of him.

This story definitely belongs in the pantheon of “worst Frontier experiences ever.”

FBI agents have identified Boulder resident Michael Allen Haag as the man who was arrested after allegedly groping female passengers and then urinating on the seatback in front of him when he was forced to move seats. The incident occurred on Frontier Flight 864 from Denver, Colorado to Charleston, South Carolina.

While Haag is likely denying the groping allegations, it will be hard for him to deny the literal photographic evidence — captured by a fellow passenger — of him sitting in his seat and urinating on the seat in front of him.

The incident apparently began when Haag was seated in a middle seat between two women. He allegedly began throwing back vodka and tonics before striking up a conversation with his neighbors. The women told investigators that he was being incredibly forward and creepy, even staring at their chests and legs. Eventually, things escalated when one of the women woke up to Haag touching her hand and leg.

Frontier flight attendants then asked the man to move to the last row of the plane. That is when Haag began urinating on the seatback in front of him in retaliation.

When one of the passengers told the flight crew what he was doing, they at first scolded her for being too loud.

“I scream, ‘he’s peeing. He’s peeing. Oh my god.’ And the flight attendant doesn’t even acknowledge him at first. Acknowledges me and says you need to calm down and stop cursing,” she said in a statement.

When the flight touched down, agents were waiting to take Michael Allen Haag into custody. He has been charged with one felony count of interfering with a flight crew and a misdemeanor charge of indecent exposure. While he was originally booked into a Charleston jail, he has since been released on his own recognizance. A federal public defender has been appointed to represent Mr. Haag.

Frontier Airlines released a statement saying that “the safety and security of our passengers is our top priority at Frontier. We have been made aware of this situation and are working with the appropriate authorities.”

The incident comes on the heels of another Frontier flight — this time from Colorado Springs to Orlando, Florida — where an out-of-control passenger punched a service dog and a pregnant woman in the stomach. The incident actually spilled out into the Orlando airport, with the pregnant woman’s fiancee tackling the assailant to the ground.

After that incident as well, Frontier released a statement stating that “the safety and security of our passengers is our top priority at Frontier. Police were immediately notified to aid in deescalating the situation.”
