Update: I called UA and went through the cancellation process, and channa is right it's the
ticket number that holds value. What's interesting is that the agent said the ticket number I should use when rebooking is the old ticket number
plus one.
Anyways, thank you to everyone who responded. It's really nice to know that I have access to a forum where I can ask travel related questions.
