Korean Air is also partners with Emirates, and offers a decent dedicated award chart starting at 30k round trip. First class from the US is a bit more pricy than it is with Alaska miles, but you can transfer 1:1 from Chase Ultimate Rewards (not Membership Rewards, sorry).

You can find their award chart here:
