The United Airlines Flight Delay Compensation Policy exists to protect passengers from unnecessary inconvenience during travel disruptions. If your flight was delayed for more than 3 hours due to airline-controlled reasons, you may qualify for financial compensation. This could apply to both domestic and international flights, especially under regulations like EU261. Make sure to keep your boarding pass, note the length and cause of the delay, and gather any relevant receipts. These steps help ensure a smooth claim process and increase your chances of receiving the compensation you're legally entitled to.
