Wait times for SEA are modeled from historical patterns. They are not a live checkpoint reading. Airports with scraped data show a Live badge.
Seattle-Tacoma International has two main security checkpoints: the Main Checkpoint in the Central Terminal and the North Checkpoint, which is closer to the N gates. Both checkpoints offer TSA PreCheck and CLEAR. The North Checkpoint is less frequently used and often provides faster throughput than the main checkpoint. Sea-Tac's single unified terminal is post-security interconnected, so either checkpoint can work regardless of your departure gate. Link Light Rail runs directly to the airport from downtown Seattle. Summer months and holiday weekends are the busiest periods.
