Not to mention the ability to book award tickets online--It's rediculous that you have to call up to check availability. Especially since for a given reward, it might be perfectly sensible to want to know the availability for CO, NW, HP, Frontier and Alaska flights. It seems that when you ask agents to check all of these, they start to lose patience. At least you can check NW/KLM/HP availability at their respective websites, so you can have some idea of what's available on these airlines before you start asking the CO agent to check too many things.
