SEA Airport Code: Seattle Airport IATA & ICAO

Seattle-Tacoma International Airport (SEA) is stored for Seattle, United States. ICAO KSEA. Timezone America/Los_Angeles. This page does not list live flights, fares or terminals.

Overview

SEA is the IATA airport code stored in this dataset for Seattle-Tacoma International Airport in Seattle, United States (US). The matching ICAO identifier is KSEA. Travel agents see SEA on tickets, baggage tags, and GDS segment city pairs (six letters, for example SEALHR when the other airport is London Heathrow). ICAO KSEA is used in flight plans and ATC, not as the two-or-three-character GDS city-pair token. The IANA timezone recorded for local GDS times at this airport is America/Los_Angeles. This code page explains how SEA is used in PNR text. It is not a live departures board. Terminal maps, contact phone numbers, lounge lists, and published flight schedules are not available in this dataset and are not invented here. Nearby airports stored for United States: JFK (New York), EWR (Newark), LGA (New York), LAX (Los Angeles), SFO (San Francisco). Related IATA city code in this dataset: SEA. To turn a booked PNR that contains SEA into a customer itinerary, paste the cryptic text into the PNR parser.

Convert and check that city and timezone match this record.
Use the airport-code page if you only need IATA versus ICAO for SEA.

Example

Example GDS segment using this airport as origin: 2 AI 101 J 12OCT 1 SEALHR HK1 0945 1510 12OCT E The parser should read SEA as departure. Times 0945/1510 are local as printed, not converted to your PC clock. If SEA is missing from the dataset, city and timezone enrichment stay empty rather than guessed.
