Hmm, just found out from my spouse that we're not using the CSR for everything, mostly recurring charges, like insurance, utilities, etc. For our upcoming trip to Europe we used our United Chase Quest points, which is our carrier of choice. Sorry for the confusion.
Regarding one way when I book on UA/Star Alliance it's almost always like this trip, into Amsterdam and return from Stockholm. And on their site you click on multi-city. I just was really making the point that if our plans change UA/Star Alliance refunds our points, no problem. Again, sorry for not being clear in the beginning.
