Hainan Airlines (HU): Airline Code for GDS PNRs
Hainan Airlines is stored in this dataset as IATA code HU and ICAO code CHH, based in China. GDS segment lines print the IATA code before the flight number. Live routes, fares and baggage policies are not in this dataset.
Overview
Hainan Airlines is stored as IATA HU and ICAO CHH, country China. The converter maps marketing carrier HU to this name when the code exists in the airline table. A typical segment starts with HU 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 China in this catalog: CA (Air China), MU (China Eastern Airlines), CZ (China Southern Airlines). Use PNR to WhatsApp or PNR to PDF after parsing if you need a customer-facing copy of a booking that includes HU.
How to use this page

- Do not add baggage or meal claims that the PNR did not print.
Example
Example segment: 2 HU 456 H 26OCT 5 WLGAKL HK1 1945 2050 The parser should set marketing carrier HU (Hainan Airlines) and flight 456. Class H is a fare bucket, not proof of cabin without the booking-class tool.
