Yep, you are in volition of the Carriage of Contract for UA
UA reserves the right to cancel bookings and/or reservations which it deems fraudulent, abusive, illogical, fictitious, which are booked and/or reserved with no intention of flying, or for which the passenger makes a misrepresentation without notice to the passenger or the individual making the booking.
UA has become increasingly strict about this. UA feels this is depriving the opportunity to sell more tickets.

Consider using SDC instead or using a different carrier for the other flight.
