I was originally booked SMF-IAH-DEN-DSM-DEN-IAH-SMF. I just got an email from United that my reservation is now SMF-ORD-DSM-ORD-SMF, which obviously makes more sense, but is significantly fewer miles! Looking for advice on what to do. Do I dare call the airline and try and get my old res back? Do I fly the new itinerary and ask for "miles as ticketed"? Anything I can do online without having to pay a change fee? I've never had this happen before. Thx in advance.
