United Airlines Check-In: Options and Guidelines for a Smooth Start United Airlines offers several convenient check-in options to streamline your travel experience. Passengers can check in online

through the United mobile app, at airport kiosks, or at staffed ticket counters. Online and mobile check-in both open 24 hours before scheduled departure and allow travelers to select seats, pay for checked baggage, and obtain digital or printable boarding passes. The United app also provides real-time updates and the option to store boarding passes directly on your smartphone, making it ideal for frequent flyers and those traveling light. At the airport, self-service kiosks are available at most major terminals, letting passengers print their boarding passes and bag tags quickly. Travelers who require special assistance, are traveling with pets, or are unaccompanied minors must complete check-in at the counter. For domestic flights, United recommends arriving at the airport at least two hours before departure, while for international travel, at least three hours is advised. The check-in window typically closes 30 minutes prior to departure for domestic flights and 60 minutes for international ones, although this may vary by airport and destination. Premium passengers, MileagePlus Premier members, and travelers in United Polaris or United First enjoy access to priority check-in lanes for faster processing. Some airports also offer United's bag drop shortcut lanes and TSA PreCheck access for eligible passengers. To maximize convenience, it’s best to check in early and review any travel requirements, especially for international destinations. United Airlines’ flexible check-in options are designed to meet the diverse needs of its global customer base, helping ensure a smooth and efficient airport experience.
