This document outlines flight procedures for Seattle-Tacoma International Airport (Sea-Tac) designed to reduce noise impacts on surrounding communities, covering both North Flow and South Flow operations. Key rules include restrictions on eastbound turns during nighttime hours (10 p.m.–6 a.m.), minimum altitude and distance requirements before turning, and designated corridors for arrivals and departures over Puget Sound and Elliott Bay. Compliance data from March 2012 shows that 89 out of 2,431 daytime South Flow eastbound arrivals turned south of the 520 Bridge early, violating the preferred procedure, with Alaska Airlines (ASA) and Southwest Airlines (SWA) accounting for the largest shares of non-compliant flights.

The total estimated cost of the realignment program ranged from $122 million to $130 million, covering capital and expense projects.

The Port of Seattle held a public open house at Sea-Tac International Airport on April 9, 2011, to present feasibility-stage proposals for reducing airport noise affecting surrounding communities. Mitigation options under consideration included building a hush house to muffle engine run-ups, installing air conditioning in uninsulated single-family homes within the updated 65 DNL noise boundary, providing sound insulation for multi-family and mobile homes, and assisting local jurisdictions with long-term land-use planning. The Port planned to submit its recommended solutions to the FAA by the end of 2011, after which the FAA would conduct a 180-day review to determine which measures it would help fund.
