Alaska is also an amazing airline, so much better than any of the other domestic carriers. If I’m connecting to SeaTac from LAX or SFO, I’ll only fly Alaska. Connecting through those airports is so prone to delays, and the Alaska staff are absolutely amazing if you miss your connection. They’re also just great in general. Singapore is the only other airline I rate as highly.
I love Alaska (and am a Gold MVP on it, and dodged doing a mileage run this year) but I will say that their delusions of competing as a major character have made them more annoying in recent years.
