Takeoff from SEA
RIGHTAs the aircraft climbs out of SEA and banks onto its eastbound heading, the right side faces south toward Mount Rainier's snow-capped cone rising above the Puget Sound lowlands and Tacoma. The left side mostly shows Everett and the flatter Sound shoreline, which is far less dramatic.

Landing at DTW
RIGHTOn the descent into DTW, the approach path swings the aircraft close enough to the east that passengers on the right can spot downtown Detroit's skyline, the Detroit River, and the western edge of Lake Erie before the final turn onto the runway. The left side shows only the flat farmland and grid-pattern suburbs of southern Michigan.
