After attending the first day of service to SeaTac Airport on a cloudy, misty day, I decided to come back out once the sun decided to show up. Luckily, Seattle weather did an about face and provided a big, yellow orb. On December 18th, Sound Transit opened the Airport Link Extension, completing the initial Central Link segment. As you read this, Sound Transit has already begun expanding the system in all directions to better serve and connect the Puget Sound.
