Yes. Alaska allows redeeming miles with their partner airlines and Emirates is one of their partners. However, it is not necessary to have Alaska credit card to redeem miles, you can simply be a member of Mileage Plan frequent flyer program. As a member, you will earn miles on Alaska Airline purchases and on partner airlines purchases. The registration in the program is free, so if you fly a lot with Alaska, you may prefer being a program member and not a cardholder. But if you prefer having their credit card, you can go to the Bank of America website to see if you can apply for the card (Bank of America issues the Alaska Airlines credit card). Also, you can compare the Alaska credit card with other travel rewards credit cards to see if there is a better option for you.
