Tickets booked with Voucher and $100 Certificate - Major Schedule Change
I booked two tickets with United. One using a DBC Free voucher and another ticket using a $100 off discount. These tickets are for the first week of September. There has been a large schedule change where the flight is leaving 2+ hours earlier (6am departure now) and also departing 2+ hours earlier.
What are my options? Will they refund my voucher and $100 off certificate if I cancel? Will they rebook me for different times if that is what I desire?
