Sorry for this question - I just can't seem to find the answer myself. I am trying to book ORD to Anchorage in late May of 2015. I am finding plenty of availability on Alaskan's website, but I don't have enough miles with them to book the flights.

I went on AA's website and they have no seats listed around my time frame - even in AAnytime first class.

I know they are part of the same alliance (or are partners?)- is there any way to use my 282,000 AA miles on Alaska?
Again, sorry for the post if it is stupid - I have been googling for a couple days and reading this site and am still unsure.
I appreciate any and all help.
Thanks!
