I frequently fly US - Germany (to HAJ or BER). Is there any carrier that allows to cross-search other (or all) *A members for award availability? I don't mind to call for the actual booking but I loathe having an agent check 55 different options for me and they usually do too.

I am piecing things together on my own right now which is fairly time intensive. I used to fly more Northwest than United and while NW/KLM have limited inventory (it outright stinks), they are well integrated.

Any pointers are much appreciated.
