If you need to file a claim with United Airlines, the process is straightforward and designed to assist passengers with issues such as delayed, damaged, or lost baggage, flight cancellations, or refunds. To begin, you can contact United Airlines customer service directly at 1-877-827-8493, where a representative can guide you through the appropriate steps based on your specific situation.

For baggage claims, you should report the issue immediately at the airport’s United Baggage Service Office or online through the United Airlines website. It's important to file the claim within 24 hours for domestic flights and within 7 days for international flights in case of damaged baggage. For delayed or lost baggage, you typically have up to 21 days to report the issue. Once your report is filed, you’ll receive a reference number to track your claim.

If you're requesting a refund due to flight cancellations, schedule changes, or service disruptions, you can submit a refund request online through the “Refunds” section on United's official website. Make sure to have your ticket number and passenger information available. For flights booked with travel credits or third-party agents, United may require additional verification.

United Airlines also allows customers to claim compensation for significant delays under specific circumstances, especially for flights to or from the European Union, where EU261 regulations apply. Be prepared to provide your flight details and documentation, such as receipts or photographs, if applicable.

You can also monitor the progress of your claim online or by calling 1-877-827-8493 to get real-time updates. United aims to resolve most claims within 7 to 14 business days, depending on the nature of the issue. Keeping copies of all correspondence and receipts will help streamline the process and ensure faster resolution.
