I've flown Alaska many times to Eugene from San Diego, and more recently from Ontario, and it's ALWAYS a good experience. The only negative experience I've had was when I connected to my smaller plane flight at Seattle, instead of Portland. Seattle's airport is under construction and it's causing a lot of delays and confusion. Avoid flying into or out of Seattle, if you can. Portland is my fav airport because of the cool vibe, the people working there, and all the great food. Alaska's people are generally wonderful and professional. The airline is also almost always on time, and they've only once sent my luggage to the wrong airport, and I promptly got it back.
