How can I select a seat on a United Airlines flight?

To select a seat on a United Airlines flight, you can use the United Airlines website or mobile app during the booking process or after making a reservation. When booking, you can choose from available seats and view the seat map to select your preferred location. If you have an existing booking, you can access your reservation online or through the app to modify your seat selection. Seat assignments may also be available at check-in, though early selection is recommended for the best options.
