1. Passenger claims men boarded flight with 'emotional support falcons' in viral tweet

In April, video footage of two men boarding their flight with “emotional support falcons” went viral on social media.

The expensive birds, which were not likely genuine support animals, got Twitter users talking about the popularity of falconry in some parts of the world, especially in the Middle East. Many airlines have policies specifically about handling birds of prey on flights.

2. Passenger delays flight, gets detained after throwing coins at engine for good luck

Passengers traveling out of Wuhan Tianhe International Airport were likely exasperated when one of their fellow passengers threw coins for "good luck" at the plane's engine and delayed their trip.

In CCTV footage of the incident, the offender was seen dropping the coins through a gap between the plane and jet bride while boarding. Three 1 yuan coins were later found on the ground near the engine.

According to a report, the man told police that his mother-in-law insisted he practice the superstitious act for a good flight, as it was his own daughter’s first time flying. He was reportedly detained for 10 days for endangering the safety of the 101 passengers on board.

“Dude would be missing toes if his foot was that close to my baby’s face,” another warned.

“Couldn’t believe my eyes … I’ve heard the legends, but never thought I would see it in real life," U.S. Olympic beach volleyball player Stafford Slick, who filmed the scene, commented of the new, rumored members of the "mile high club."
