Michael Hohl and Amber Maxwell had boarded their flight when they noticed a passenger napping across the row they were supposed to be sitting in.
Instead of waking up the snoozing man, the pair decided to sit a few rows in front of their assigned seats.
Hohl said that after he and Maxwell sat down, a flight attendant asked if they were in their assigned seats. When the couple said no and explained why they had moved, Hohl said the attendant declined their request for an upgrade and asked them to return to their original seats.
Hohl said that although he and Maxwell did as they were told, a U.S. Marshall later boarded the flight and asked them to get off the plane.
6. United Airlines CEO's heart transplant comes under scrutiny
Following United Airlines CEO Oscar Munoz's apology over Flight 3411, people began questioning whether his wealth played a role in the heart transplant he received last year.
Munoz had a heart attack on October 15, 2015, one month after he took over as United's new CEO.
Less than three months later, he received a new organ.
Since the waiting list for a new heart was reportedly up to 4,200 people at the time, questions have risen about how he was able to get a new heart without waiting very long.

Apparently another passenger, who Furfey says was "obviously inebriated," expressed concern to an airline employee that the fair-skinned child didn't look like her Mexican father, raising suspicion that he had kidnapped her.
The mother of three says she burst into tears when she learned the details of what her family had gone through.

9. Woman claims United Airlines employee forced her to back of plane in tears without explanation
A New York woman filed a $150,000 lawsuit against United Airlines, claiming she was forced from her business class seat to the back of the plane by an employee without any explanation during a flight last year.
Karen Shiboleth, a 24-year-old Columbia graduate, was traveling to London to attend a master's degree program at Kings College on September 10, 2016.
Shiboleth claims that ten minutes prior to take off, a United employee boarded the craft and demanded she vacate her seat in United BusinessFirst and move to the back of the plane.
The lawsuit alleges that nobody would explain to Shiboleth why she was being moved, and that when she expressed her confusion, the employee took her arm "without consent" and forced her to a middle seat in the back of the plane.
To make matters worse, the unidentified worker reportedly called her a "c--t" during the interaction, bringing Shiboleth to tears.

11. Giant rabbit mysteriously dies aboard United Airlines flight
Simon, a 35-inch behemoth, was traveling from London's Heathrow to Chicago's O'Hare to meet his new "celebrity owner" when he mysteriously died in the airline's care.
Annette Edwards, Simon's breeder, says that both she and Simon's buyer are extremely upset and confused by the incident.
"Simon had a vet's check-up three hours before the flight and was fit as a fiddle," Edwards said. "Something very strange has happened and I want to know what. I've sent rabbits all around the world and nothing like this has happened before."
Simon was the son of the world's current largest rabbit, Darius, who is a whopping 51 inches long.
The 10-month-old rabbit was reportedly on track to out grow his father and eventually steal his title.
Instead, the family was met with a Great Dane they had never seen before. Apparently, a United mix-up had sent Irgo all the way to Japan, which is where the Great Dane was meant to go.

In addition, pets on United flights suffered more injuries over the last three years than on any other airline.

A spokesperson for United told The Associated Press that it was not known why the stewardess did not put Kokito under Robledo's seat.
Robledo’s tickets were refunded along with the $200 fee charged for carrying a pet.
