Thank you.
Yes and yes. However, UA will not allow you to change to the same flight you're currently on. Therefore, you either need to (a) change to another flight and then back to your current flight, or (b) cancel, then start fresh, as if you were booking a new reservation, and then apply the flight credit during the checkout process.
