SIN Airport Code: Singapore Airport IATA & ICAO
Singapore Changi Airport (SIN) is stored for Singapore, Singapore. ICAO WSSS. Timezone Asia/Singapore. This page does not list live flights, fares or terminals.
Overview
SIN is the IATA airport code stored in this dataset for Singapore Changi Airport in Singapore, Singapore (SG). The matching ICAO identifier is WSSS. Travel agents see SIN on tickets, baggage tags, and GDS segment city pairs (six letters, for example SINLHR when the other airport is London Heathrow). ICAO WSSS 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 Asia/Singapore. This code page explains how SIN 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 Singapore: none stored in this country slice. Related IATA city code in this dataset: SIN. To turn a booked PNR that contains SIN into a customer itinerary, paste the cryptic text into the PNR parser.
How to use this page
- Confirm the three-letter token on the ticket or PNR is SIN, not a similar code.
- Open the PNR parser and paste the full itinerary that contains SIN.
- Convert and check that city and timezone match this record.
- Use the airport-code page if you only need IATA versus ICAO for SIN.
- Do not copy terminal or lounge claims from other websites onto this page. They are not stored here.
Example
Example GDS segment using this airport as origin: 2 AI 101 J 12OCT 1 SINLHR HK1 0945 1510 12OCT E The parser should read SIN as departure. Times 0945/1510 are local as printed, not converted to your PC clock. If SIN is missing from the dataset, city and timezone enrichment stay empty rather than guessed.
