Singapore Airlines (SQ): Airline Code for GDS PNRs
Singapore Airlines is stored in this dataset as IATA code SQ and ICAO code SIA, based in Singapore. GDS segment lines print the IATA code before the flight number. Live routes, fares and baggage policies are not in this dataset.
Overview
Singapore Airlines is stored as IATA SQ and ICAO SIA, country Singapore. The converter maps marketing carrier SQ to this name when the code exists in the airline table. A typical segment starts with SQ plus a numeric flight number and a booking class letter. This article is not an airline homepage: schedules, change fees, and loyalty rules are omitted because they are not stored and must not be invented. Peer carriers from Singapore in this catalog: TR (Scoot). Use PNR to WhatsApp or PNR to PDF after parsing if you need a customer-facing copy of a booking that includes SQ.
How to use this page

- Do not add baggage or meal claims that the PNR did not print.
Example
