Pro Tips for SEA Travelers
- Link Light Rail is the obvious choice for Seattle — it stops right in the terminal and avoids I-5 and SR-99 traffic.
- The Satellite Terminal (S) is reached by an underground train; budget extra time if connecting through Sea-Tac with tight connections.
- Alaska's Concourse C and D are well-organized and have great Pacific Northwest food options; plan to arrive early and enjoy them.
- Sea-Tac's parking garage fills quickly during holidays; use the third-party Spot Hero or ParkWhiz apps to find cheaper off-site lots.
- Weather delays are more common in winter than fog; Seattle's rain rarely grounds flights but fog in the Cascade passes can affect connections.
- The Amex Centurion Lounge (between A and B) is one of the best in the network — timed passes are a must during busy periods.
- If departing from the S Satellite, expect a 10-minute underground train ride from security check — factor this into your timeline.
