I'm am having the hardest time finding a Business class award ticket from SEA to CPT. I used to be able to find availability fairly easy. In the past year I haven't found anything. I can sometimes find something in one direction but not the other. And of course I want to use as few miles as possible. I'm hoping to use somewhere between 120-150K.

I have sufficient miles on most of the major US airlines. Also have in excess of 140K star points.

I want to avoid using BA because of the excessive surcharges. (could perhaps use their partner, Comair from JNB to CPT)

"I" can never find any low tier availability on Delta (I know there is a Delta thread regarding low tier awards, but apparently from SEA, they are more difficult to get)

I am flexible on dates and am not completely locked into a business award.

Are there one or two airlines I should concentrate on?

Thanks for your help
