North Flow Operations Sample Flight Track Map

Winds from the north 

When winds are from the north, aircraft will depart the airport in a northerly direction and arriving aircraft will approach from the south. This operation occurs most commonly during the warmer, sunnier periods of the year.

A map titled “SEA Airport North Flow Operations Sample Map” showing aircraft flight activity over the greater Seattle region. The background is a beige‑colored map displaying cities, major roads, and waterways, including Puget Sound and Lake Washington. Numerous flight‑path lines cover the map: red lines represent jets and propeller arrivals, and green lines represent jets and propeller departures. The lines converge densely around the airport near the bottom center and extend in many directions to the north, east, and west. Black airplane icons are placed along several flight paths to illustrate aircraft movement. A legend at the bottom identifies the red and green line types, and a compass rose beneath it indicates north, south, east, and west. The bottom right corner contains the year “2024.
