How do I use the Skip Waitlist

United Airlines provides various services, including an upgrade waitlist through which one can request an upgrade to a higher cabin. Moreover, the airline also allows passengers to upgrade the flight without waiting in the waitlist through the United Plus Points Skip Waitlist feature. But this service is available only on international flights, and it is a non-refundable service. Further, there are multiple ways to use the skip waitlist on United. Passengers can add it either at the time of booking the flight or after the reservation from the my trip section.
