When I look up award avilability for YQR-ORD-BRU (UA 6912/972) for September 17/10 on Expert Flyer I find F6 and F4 for First availailability. I don't see anything showing when I search on KVS. Is it the difference in access methods that produces the different result? Or, is it actually the type of reward space that is showing that is different (e.g., UA space versus Star Alliance space)? These questions may be answered elsewhere, but I haven't found answers yet but I am curious about the differences between what is being shown.
Thanks.
