The Washington city has battled poor air quality for the past two weeks. Authorities said yesterday that winds would likely push the smoke away from Seattle, but later announced the air quality alerts issued across Western Washington were getting extended to Thursday at noon.

This was Alaska Airlines flight 447 flying out of LAX (Los Angeles) to SeaTac, Wednesday August 22nd. This video was taken during descent, around 5:35 pm Pacific Standard Time, a few minutes before touchdown.
