Change your flights within 24 h (both the original and new departure times) if the same booking class is available for the new flight. If you have United Premier Gold (and above) status, there is no change fees. Otherwise, it will cost $75. Here is a thread on UA forum. http://www.flyertalk.com/forum/united-airlines-mileageplus/1816718-ua-same-day-travel-change-sdc-fees-questions-wiki-2017-forward.html
