Hi All, I have a roundtrip planned for a December departure on a UA-SAS Codeshare (UA for domestic legs, SAS for European legs, return in January). I booked the flights through Chase's Ultimate Rewards travel service, so before purchasing I called to find out the fare class of the SAS legs because I wanted to make sure that I received 100% credit for the miles. (Learning from prior experience that not all Codeshares give 100% mileage credit.) I found out that the SAS legs are K fare class, checked the chart on .bomb and confirmed that K fare class receives 100% mileage. Then I proceeded with the purchase. The flights are showing up in my UA account and the SAS legs are indeed fare class K. However, the reservation is telling me that these legs only receive 25% mileage credit. These are ORD-ARN-ORD flights, so are 4000+ miles each way. We're talking the difference between 2,000 and 8,000 miles for the entire trip, which is a lot for me and can mean the difference between elite status and no status. I called UA and after several reps and two or three different stories, asked for a supervisor. With some research she determined that the credit for these flights PRE-MERGER would have been just 25%. She concluded that the system hasn't been fully upgraded and is still reflecting this partial crediting, but assured me that their current charts are correct and that I should receive 100%. She said that if SAS does not give me full mileage credit, then UA will file an appeal on my behalf, but said that there is nothing that UA can do now since the miles "come from SAS." I asked her to make a note in my account in case there were problems later. I also took screen shots of the current mileage chart for my CYA file. An SAS rep confirmed that that K fares receive 100% mileage credit, which did help to ease my mind. Questions: 1) Should I be doing anything else at this point to ensure that I'm covered? 2) Has anyone else experienced something similar and, if so, how did it turn out? The outbound flight is in late December, so I won't have time in 2012 to make up any mileage differences. All feedback is appreciated. Thanks!
