WestJet Airlines Ltd. is Canada's second-largest air carrier, headquartered in Calgary, Alberta, operating scheduled passenger service to more than 100 destinations across Canada, the United States, Mexico, Central America, the Caribbean, Europe and Asia, alongside WestJet Encore, WestJet Vacations, WestJet Cargo and the Sunwing Vacations Group. In the distribution chain WestJet sits upstream of the agency channel: its inventory reaches travel sellers today through EDIFACT in the Amadeus, Sabre and Travelport GDSs, and it is standing up an IATA NDC surface (schema 17.2 and 21.3/24.1) built and hosted on Accelya's FLX/Farelogix platform, with a stated Q4 2026 rollout. Its API posture is honest but closed: there is no public developer portal, no self-serve signup, no OpenAPI or WSDL and no consumer API. The WestJet Direct Connect API is documented only as a public capability matrix at westjetndc.com, and access requires an IATA or ARC accreditation number (TIDS is explicitly not supported), a business-type and sales-volume qualification form, and WestJet approval. Agency booking through WestJet Agent Direct likewise requires an IATA/TIDS/ARC number and a five-to-ten business day review. There is no bulk export for agency or booking data; guest data comes out only via a verbally authenticated PIPEDA-style "Guest information report" request.
