Sorry if this question is covered elsewhere, but I have not been able to find it. I have an award ticket on LH from FCO to EWR on 11/24. It was booked with UA miles as a business saver award. My plans have now changed. Instead, I now need to travel from FCO to ORD on 12/13. There seem to be plenty of business saver awards available. What is the best way to make this change? Cancel ticket, redeposit, and reserve a new ticket? Or, call and attempt to change the ticket I already have? Any advice would be much appreciated. Thanks in advance.
