Air travel is a hot mess. Here are 7 of the most chaotic, head-scratching stories from this summer.

In June, Argentinian newspaper La Nacion reported that a flight attendant with Aerolíneas Argentinas made a bomb threat before a Miami-bound flight on May 21.

The outlet reported that federal judge Federico Villena identified the flight attendant as Daniela Carbone, and said she made the threat with her daughter's cell phone and used voice distortion software to hide her identity.

Clarín, an Argentinian newspaper, said Carobone's ex-boyfriend and his new girlfriend worked as cabin crew on the flight. Argentina's Airport Security Police arrested Carobine at Ezeiza International Airport in Buenos Aires on charges of aggravated coercion, public intimidation, and hindering public service. Carbone faces six years in jail if found guilty, the outlet reported.

Representatives for Aerolíneas Argentinas did not respond to Insider's request for comment.

A man was arrested during a flight from Mumbai to New Delhi after urinating and defecating on an Air India plane's floor mid-flight, outlets including The Independent and The Times of India reported.

An Air India spokesperson did not share specifics with Insider but confirmed in a statement that a passenger "behaved in a repulsive manner, causing discomfort to the co-passengers."

"In doing their best to manage the situation in the circumstances, the crew immediately secluded the passenger for the rest of the flight and issued a warning. The passenger was handed over to the security personnel upon landing in Delhi," the spokesperson added.

According to an affidavit filed in the US District Court for the District of Alaska, a man was heard screaming in the bathroom before punching the door open and approaching the cockpit with "drool and foam coming out of his mouth."

A flight attendant told prosecutors he blocked the man's advances and asked for a medical expert on board for help. A nurse suggested administering Narcan, which treats drug overdoses, but this caused the man to become combative.

The affidavit said the man "tried to punch and push on people and grab onto them. Three male passengers got up from their seats and came up to the front of the plane to assist."

The man was handcuffed and given sedation medication, according to the affidavit. He told witnesses he was having a panic attack, not an overdose.

The unnamed man faces several charges, including simple assault within the maritime and territorial jurisdiction.

"We do not comment on incidents involving pending litigation," a representative for Alaska told Insider. "We are extremely thankful to our crew members on board Alaska Airlines Flight 183 on June 24 who kept other passengers safe and calm during a troubling situation."

According to French newspaper Le Parisien, a United Airlines pilot showed up to work under the influence of alcohol and had a blood-alcohol level of 0.132%, which is three times the Federal Aviation Administration's limit.

The Local reported that the 63-year-old American pilot told a French court that he only drank two glasses of wine the night before, but authorities said the pilot was "showing signs of obvious drunkenness" when he arrived for work at 3 p.m. on July 23.

"He was staggering slightly, his eyes were glassy, and his mouth pasty," a police officer told The Local. The outlet added that the pilot was fined 4,500 euros and his pilot license was suspended for a year in addition to his prison sentence.

A United Airlines spokesperson told Insider: "The safety of our customers and crew is always our top priority. We hold all our employees to the highest standards and have a strict no-tolerance policy for alcohol. This employee was immediately removed from service and we are fully cooperating with local authorities."

Authorities told the Scottish Sun and Canarian Weekly in August that a Ryanair flight was en route to the Canary Islands from Edinburgh, Scotland, when two male family members began "beating each other." The outlets reported that the drunken brawl forced the pilot to make an emergency landing in Faro, Portugal, where authorities waited.

"This flight from Edinburgh to Gran Canaria (04 Aug) diverted to Faro after a small number of passengers became disruptive onboard," a representative for Ryanair told Insider. "Crew called ahead for police assistance and the passengers were removed from the aircraft by local police before this flight continued safely to Gran Canaria. We sincerely apologize to affected passengers for any inconvenience caused as a result of these passenger's disruptive behavior."
