HU Airline Code: Hainan Airlines IATA & ICAO
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
HU is the IATA airline designator stored for Hainan Airlines. ICAO is CHH. Country of record: China. On a cryptic GDS line the IATA code sits immediately before the flight number, for example HU 456. Agents should not confuse HU (two characters, sometimes a digit such as 6E) with CHH (three letters). This code page does not list routes, alliances, baggage rules, or fleet. Those facts are not in the dataset. Other China carriers stored here: CA (Air China), MU (China Eastern Airlines), CZ (China Southern Airlines). To decode a full itinerary that markets HU, paste the PNR into the parser.
How to use this page
- Find HU at the start of the flight line in the PNR.
- Paste the full itinerary into the PNR parser (or the GDS-specific parser if you know the host).
- Confirm the carrier name resolves to Hainan Airlines.
- 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.
