SEA,SEA,SEA. Landing at the N terminal is a pain. Landing at the end of D or C and having to move to the other end is a pain. Car rental shuttle is a long hike and too far out. They should of connected to the light rail. Proactive cancellations when having to connect. The FAA cancelled my AS flight connecting through SEA this winter with a chance of snow flurries (no snow anywhere). Booked Delta with almost the same times and had no issue.
