I'm in the process of scheduling a trip to Indonesia in October of this year and was looking at booking a "B" or "Y" class ecomony ticket and then use some of my United mile to upgrade into business. However, in talking with Singapore I was advised that they were not allowing tickets to be upgraded with outside Star Alliance points/miles. The people I spoke to at Singapore stated it was due to equipment size and safety reasons and could not get to a supervisor to discuss this either. I was wondering if anyone else had run into this issue recently?
I have not been able to get an answer from United/Cont. yet about this issue.
