British Airways NDC API
British Airways' IATA New Distribution Capability API - a direct link into BA's host reservation system for flight shopping, ordering, ticketing and post-booking servicing, operated jointly across IAG for BA and Iberia. It implements the IATA EDIST message set (the ndc.ba.com application carries the XML namespace http://www.iata.org/IATA/EDIST/2017.2), with a 21.3 pilot programme running alongside the 17.2 production version. The IAG developer portal described the 17.2 plan as AirShopping, OfferPrice, SeatAvailability, OrderCreate, OrderRetrieve, AirDocIssue, OrderChange, OrderReShop and OrderChangeNotif. No OpenAPI or WSDL is published, no production base URL is published, and there is no self-serve access - see review.yml for the full certification and contracting path.
