United Airlines offers passengers multiple convenient ways to check in for their flights. Online check-in is available through the United Airlines website or mobile app, starting 24 hours before departure. During online check-in, travelers can select seats, pay for baggage, and receive a mobile boarding pass. Self-service check-in kiosks are available at airports, allowing passengers to print boarding passes, check bags, and more. For those who prefer assistance, ticket counter check-in is an option. Check-in deadlines vary by flight type but generally close 30 minutes before domestic flights and 60 minutes before international flights. Travelers must provide booking details and valid identification. It's important to check United Airlines' website for any specific COVID-19-related guidelines or requirements.
