If you have enough posts to get you into the Coupon Connection forum, you can also trade the codes for something else that would be useful to you like hotel points or upgrades on another airline you might be flying...it's worth noting, that for whatever reason, AS upgrades (unlike UA and AA upgrades) seem to be the *least* traded on CC (maybe due to the smaller number of AS elites and/or the fact that the AS upgrades dropped in value due to the fare restriction that got added to them).
