Alaska airline has best boarding and baggage policy.
ShirleyFlew with Alaska AirlinesSEA-ORDJun 2024
I generally fly United or Delta out of South Bend, IN into Seattle or wherever I'm going. I have no issues with Alaska. I only use Alaska when flying with my family from the Seattle area back to Chicago O'Hare and then we drive to SW Michigan where I live. Alaska Airlines has a beautiful new terminal at SeaTac as well. A good airline. I do like planes that have screens on the back of the seats.

Budget if you’re planning on shopping for meals or souvenirs at Sea-Tac, it’s not cheap.
