#1 United Airlines' Dragging Incident
Perhaps the most infamous incident involving United Airlines occurred in April 2017, when a passenger named Dr. David Dao was forcibly removed from a flight. The incident, which was caught on camera and shared widely on social media, sparked widespread outrage and negative publicity for the airline. United Airlines CEO Oscar Munoz initially defended the airline's actions, but later issued a public apology and announced changes to the company's policies.
#2 United Airlines Pet Deaths
In 2018, United Airlines faced criticism after several incidents involving the deaths of pets during flights. The airline was found to have the highest number of animal deaths of any U.S. airline that year, leading to calls for improved regulations and oversight of animal transport on airplanes.
#3 United Airlines' Leggings Controversy
In March 2017, United Airlines faced backlash after two teenage girls were prevented from boarding a flight because they were wearing leggings. The airline's dress code policy for passengers traveling on company passes came under scrutiny, with many accusing the airline of sexism and discrimination.
#4 United Airlines' overbooking policies
United Airlines has also faced criticism for its overbooking policies. In 2017, a passenger named Dr. David Dao was forcibly removed from an overbooked flight, an incident that sparked widespread public outrage and negative publicity for the airline. United Airlines later announced changes to its overbooking policies in an effort to prevent similar incidents from occurring in the future.
#5 United Airlines' Mistreatment of Musicians
In March 2020, United Airlines faced criticism after a video surfaced of the airline breaking a musician's $30,000 cello. The incident led to calls for better treatment of musicians and their instruments during flights.
To help mitigate the risk of overbooking and other issues, United Airlines has implemented the "united airlines manage my trips" feature on its website, allowing customers to easily view and manage their upcoming reservations.
These are some of the most notable controversies and incidents involving United Airlines in the past. While the airline has taken steps to address these issues and improve its policies, it's crucial for the company to continue to review and improve its procedures to ensure the safety, comfort and rights of its passengers are protected and to keep its reputation as a safe and reliable airline.
