Very helpful link, thank you

But why is everyone so snarky? I use FT to offer guidance where I have expertise and seek guidance where I don't. Seems to me that's the purpose of it. I apologize I'm not as knowledgeable as others here in regards to using UA points to upgrade on *A airlines. And also I find the search tool to be quite lacking and have difficulty finding links like the one you found. Obviously if I was able to find it I wouldn't need to ask for help. But I didn't. Now I have it and should be all set. Again, thank you for making my life a little easier. I hope I can return the favor on the board someday in my areas of expertise ^
