Sorry for the rather basic question, as I want to be clear on this new policy, but I am looking at booking a one way flight using Mileageplus miles but haven't confirmed the date exactly.
If I booked two different one way flights using miles, I can cancel either of them up to the last minute without any fees or problems and the miles will go back into my account free?

is that correct?

Thanks in advance!
