The layout is poor (too many passenger bottlenecks), the over-night parking expensive, it appears old and the flooring looks like it's straight out a fifth grade class room. Who ever decided that earth tones made sense with all of the grey in the skies of Seattle should have their head examined. The restaurants are bland, the gift shops mediocre but there are a variety coffee shops everywhere. So for caffeine freaks, this place is great. I've certainly seen worse than Sea-Tac (JFK, Midway, etc.) but it could be so much better. Hopefully the expansion will improve the place because as it stands today...none of the charm and beauty of the Northwest lives in this airport.
