Alaska Airlines announced a new codeshare agreement with Iberia Airlines, a fellow member of the oneworld alliance. The agreement allows passengers on Iberia to book travel and easily connect to more than 40 routes throughout Alaska's network for travel on or after Oct. 7. On the West Coast, Iberia has nonstop service between Los Angeles and its Madrid hub, and seasonal service between San Francisco and Barcelona – enabling seamless connectivity to the Alaska network beyond both California cities. Alaska launched its partnership with Iberia on March 31, 2021, the same day Alaska formally became a member of the oneworld global alliance. The partnership enables Alaska’s Mileage Plan members to earn miles on Iberia flights and features reciprocal elite benefits, including preferred seat selection; priority check-in, security clearance and boarding; lounge access; and extra baggage allowance, with further enhancements coming over the next several months.
